Summary Clinical characteristics. Werner syndrome is characterized by the premature appearance of features associated with normal aging and cancer predisposition. Individuals with Werner syndrome develop normally until the end of the first decade. The first sign is the lack of a growth spurt during the early teen years. Early findings (usually observed in the 20s) include loss and graying of hair, hoarseness, and scleroderma-like skin changes, followed by bilateral ocular cataracts, type 2 diabetes mellitus, hypogonadism, skin ulcers, and osteoporosis in the 30s. Myocardial infarction and cancer are the most common causes of death; the mean age of death in individuals with Werner syndrome is 54 years.
A number sign (#) is used with this entry because Werner syndrome is caused by homozygous or compound heterozygous mutation in the RECQL2 gene (604611), which encodes a homolog of the E. coli RecQ DNA helicase, on chromosome 8p12. See also Hutchinson-Gilford progeria syndrome (HGPS; 176670), a more severe progeroid syndrome with earlier onset caused by mutation in the LMNA gene (150330). Clinical Features The features of Werner syndrome are scleroderma-like skin changes, especially in the extremities, cataract, subcutaneous calcification, premature arteriosclerosis, diabetes mellitus, and a wizened and prematurely aged facies. A particularly instructive pedigree was reported by McKusick (1963). The habitus is characteristic, with short stature, slender limbs, and stocky trunk. The nose is beaked. Epstein et al. (1966) studied a Japanese patient living in Seattle.
Werner syndrome (WS) is a rare inherited syndrome characterized by premature aging with onset in the third decade of life and with cardinal clinical features including bilateral cataracts, short stature, graying and thinning of scalp hair, characteristic skin disorders and premature onset of additional age-related disorders. Epidemiology The prevalence among Japanese and Sardinian populations is estimated to be 1/50,000 due to the presence of founder mutations. Prevalence in other populations is unknown, but may be around 1/200,000. Clinical description WS patients are normal at birth and during childhood, apart from the absence of a pubertal growth spurt. WS presents between the ages of 20 and 30 with major symptoms of early onset bilateral cataracts, thinning and graying of the hair, short stature and skin changes (ankle ulceration, hyperkeratosis, tight skin, age spots, ''bird-like'' facies and subcutaneous atrophy).
Werner syndrome is characterized by the dramatic, rapid appearance of features associated with normal aging. Individuals with this disorder typically grow and develop normally until they reach puberty. Affected teenagers usually do not have a growth spurt, resulting in short stature. The characteristic aged appearance of individuals with Werner syndrome typically begins to develop when they are in their twenties and includes graying and loss of hair; a hoarse voice; and thin, hardened skin. They may also have a facial appearance described as "bird-like." Many people with Werner syndrome have thin arms and legs and a thick trunk due to abnormal fat deposition.
Werner syndrome is a condition that causes premature aging. People with this syndrome will develop and grow normally until puberty. At puberty, growth stops and adults with Werner syndrome are typically shorter than average. By the early 20s-30s, people with this syndrome develop conditions usually associated with more advanced ages. In addition, people with Werner syndrome have an increased risk of developing cancer, especially thyroid and skin cancers. Heart attack and cancer are the most common causes of death. Werner syndrome is caused by mutations in the WRN gene and is inherited in an autosomal recessive manner.

A number sign (#) is used with this entry because familial spinal neurofibromatosis is caused by heterozygous mutation in the neurofibromin gene (NF1; 613113) on chromosome 17q11. Description Spinal neurofibromatosis is an autosomal dominant disorder characterized by a high load of spinal tumors. These tumors may be asymptomatic or result in neurologic symptoms, including back pain, difficulty walking, and paresthesias. Spinal NF is considered to be a subtype of neurofibromatosis type I (NF1; 162200), which is an allelic disorder. Patients with spinal NF may or may not have the classic cutaneous cafe-au-lait pigmentary macules or ocular Lisch nodules typically observed in patients with classic NF1.
A number sign (#) is used with this entry because neurofibromatosis type I (NF1) is caused by heterozygous mutation in the neurofibromin gene (NF1; 613113) on chromosome 17q11. Description Neurofibromatosis type I is an autosomal dominant disorder characterized by cafe-au-lait spots, Lisch nodules in the eye, and fibromatous tumors of the skin. Individuals with the disorder have increased susceptibility to the development of benign and malignant tumors. NF1 is sometimes referred to as 'peripheral neurofibromatosis.' The worldwide incidence of NF1 is 1 in 2,500 to 1 in 3,000 individuals (reviews by Shen et al., 1996 and Williams et al., 2009). Type II neurofibromatosis (NF2; 101000) is a genetically distinct disorder caused by mutation in the gene encoding merlin (NF2; 607379) on chromosome 22q12.
Summary Clinical characteristics. Neurofibromatosis 1 (NF1) is characterized by multiple café au lait spots, axillary and inguinal freckling, multiple cutaneous neurofibromas, iris Lisch nodules, and choroidal freckling. About half of people with NF1 have plexiform neurofibromas, but most are internal and not suspected clinically. Learning disabilities are present in at least 50% of individuals with NF1. Less common but potentially more serious manifestations include optic nerve and other central nervous system gliomas, malignant peripheral nerve sheath tumors, scoliosis, tibial dysplasia, and vasculopathy. Diagnosis/testing. The diagnosis of NF1 is usually based on clinical findings.
Neurofibromatosis type 1 is a condition characterized by changes in skin coloring (pigmentation) and the growth of tumors along nerves in the skin, brain, and other parts of the body. The signs and symptoms of this condition vary widely among affected people. Beginning in early childhood, almost all people with neurofibromatosis type 1 have multiple café-au-lait spots , which are flat patches on the skin that are darker than the surrounding area. These spots increase in size and number as the individual grows older. Freckles in the underarms and groin typically develop later in childhood.
Neurofibromatosis type 1 (NF1) is a genetic condition that affects the skin, the skeleton and the part of the nervous system outside the brain and spinal cord peripheral nervous system). The main signs and symptoms of NF1 include dark colored spots on the skin (café-au-lait spots), benign growths along the nerves (neurofibromas), and freckles in the underarm and groin. Other symptoms may include colored spots in the eye (Lisch nodules), curvature of the spine, learning disabilities, and an increased risk for cancer. The number of neurofibromas typically increases over time, and some can get large or turn cancerous and need to be removed. The severity and symptoms can vary greatly from person to person. This condition is caused by genetic changes ( DNA variants ) in the NF1 gene and is inherited in an autosomal dominant pattern.
Neurofibromatosis type 1 (NF1) is a clinically heterogeneous, neurocutaneous genetic disorder characterized by café-au-lait spots, iris Lisch nodules, axillary and inguinal freckling, and multiple neurofibromas. Epidemiology Prevalence is reported to be 1/3,000 live births. NF1 is reported in many ethnic groups and affects males and females equally. Clinical description The clinical features are highly variable, even within the same family. Multiple café-au-lait macules are found in almost all patients (some at birth and most before the first year). Intertriginous freckling develops starting at 5 years of age. Multiple cutaneous and subcutaneous neurofibromas develop in adults.

Trichinellosis is a zoonotic parasitic disease caused by the consumption of raw or undercooked meat (pork and wild game) infected by nematodes of the genus Trichinella and that is characterized by an enteral (intestinal) phase, that can be asymptomatic or that can manifests with diarrhea, nausea, vomiting and abdominal pain, and a parenteral (muscular) phase, manifesting with fever, periorbital edema, muscle swelling and pain, weakness, and in some cases, skin rash and peripheral edema. Rarely, potentially fatal cardiac (i.e. myocarditis), pulmonary (i.e. pneumonitis, respiratory failure), and nervous system (i.e. meningoencephalitis) complications may occur.
Overview Trichinosis (trik-ih-NO-sis), sometimes called trichinellosis (trik-ih-nuh-LOW-sis), is a type of roundworm infection. These roundworm parasites (trichinella) use a host body to live and reproduce. These parasites infect animals such as bears, cougars, walruses, foxes, wild boars and domestic pigs. You get the infection by eating the immature form of the roundworm (larvae) in raw or undercooked meat. When humans eat raw or undercooked meat containing trichinella larvae, the larvae grow into adult worms in the small intestine.
A number sign (#) is used with this entry because susceptibility to allergic rhinitis has been associated with polymorphisms in the IL13 gene (147683) on chromosome 5q31 and the FOXJ1 gene (602291) on 17q25. Clinical Features Allergic rhinitis is a common disease of complex inheritance and is characterized by mucosal inflammation caused by allergen exposure. Allergic rhinitis often affects patients with other coexisting manifestations of allergy such as asthma (600807) and atopic dermatitis (603165). Molecular Genetics Wang et al. (2003) found a significant association of the IL13 arg130-to-gln (R130Q) SNP (147683.0002) with serum total IgE levels in Chinese adult patients with allergic rhinitis. Patients with a gln/gln genotype showed much higher serum total IgE than those with an arg/arg genotype.

Description Systemic sclerosis is a clinically heterogeneous connective tissue disorder characterized by immune activation, vascular damage, and fibrosis of the skin and major internal organs. Clinical and experimental data suggest that the disorder is multifactorial, involving both genetic and environmental factors (Fonseca et al., 2007). Gabrielli et al. (2009) provided a detailed review of scleroderma, including clinical manifestations and pathophysiology. See also Reynolds syndrome (613471), which shares some clinical features with scleroderma and CREST syndrome. Clinical Features Greger (1975) described 3 males, including father and son, with progressive systemic scleroderma (systemic sclerosis) in an inbred triracial isolate of southern Maryland, known as the Brandywine group.
Systemic sclerosis (SSc) is a generalized disorder of small arteries, microvessels and connective tissue, characterized by fibrosis and vascular obliteration in the skin and organs, particularly the lungs, heart, and digestive tract. There are two main subsets of SSc: diffuse cutaneous SSc (dcSSc) and limited cutaneous SSc (lcSSc) (see these terms). A third subset of SSc has also been observed, called limited Systemic Sclerosis (lSSc) or systemic sclerosis sine scleroderma (see these terms). Epidemiology The prevalence is estimated at about 1/6,500 adults. Women are predominantly affected (F/M sex ratio around 4:1). Clinical description The disease usually manifests between 40 and 50 years of age.
Systemic scleroderma is an autoimmune disorder that affects the skin and internal organs. It is characterized by the buildup of scar tissue (fibrosis) in the skin and other organs. The fibrosis is caused by the body's production of too much collagen, which normally strengthens and supports connective tissues. The signs and symptoms of systemic scleroderma usually begin with episodes of Raynaud's phenomenon , which can occur weeks to years before fibrosis. This may be followed by puffy or swollen hands before the skin becomes thickened and hard.
Overview Thalassemia (thal-uh-SEE-me-uh) is an inherited blood disorder that causes your body to have less hemoglobin than normal. Hemoglobin enables red blood cells to carry oxygen. Thalassemia can cause anemia, leaving you fatigued. If you have mild thalassemia, you might not need treatment. But more severe forms might require regular blood transfusions. You can take steps to cope with fatigue, such as choosing a healthy diet and exercising regularly. Symptoms There are several types of thalassemia. The signs and symptoms you have depend on the type and severity of your condition.
Thalassemia is an inherited blood disorder that reduces the production of functional hemoglobin (the protein in red blood cells that carries oxygen). This causes a shortage of red blood cells and low levels of oxygen in the bloodstream, leading to a variety of health problems. There are two main types of thalassemia, alpha thalassemia and beta thalassemia . Signs and symptoms vary but may include mild to severe anemia, paleness, fatigue , yellow discoloration of skin (jaundice), and bone problems. Beta thalassemia is caused by changes (mutations) in the HBB gene while alpha thalassemia is caused by mutations in the HBA1 and/or HBA2 genes.
Summary Clinical characteristics. Xeroderma pigmentosum (XP) is characterized by: Sun sensitivity (severe sunburn with blistering, persistent erythema on minimal sun exposure in ~60% of affected individuals), with marked freckle-like pigmentation of the face before age two years in most affected individuals; Sunlight-induced ocular involvement (photophobia, keratitis, atrophy of the skin of the lids); Greatly increased risk of sunlight-induced cutaneous neoplasms (basal cell carcinoma, squamous cell carcinoma, melanoma). Approximately 25% of affected individuals have neurologic manifestations (acquired microcephaly, diminished or absent deep tendon stretch reflexes, progressive sensorineural hearing loss, and progressive cognitive impairment). The most common causes of death are skin cancer, neurologic degeneration, and internal cancer. The median age at death in persons with XP with neurodegeneration (29 years) was found to be younger than that in persons with XP without neurodegeneration (37 years). Diagnosis/testing. The diagnosis of XP is made on the basis of clinical findings and family history and/or by the identification of biallelic pathogenic variants in DDB2 , ERCC1 , ERCC2 , ERCC3 , ERCC4 , ERCC5 , POLH , XPA , or XPC .
A number sign (#) is used with this entry because xeroderma pigmentosum complementation group D (XPD) is caused by homozygous or compound heterozygous mutation in the excision repair gene ERCC2 (126340) on chromosome 19q13. Description Xeroderma pigmentosum is a rare autosomal recessive disorder characterized by acute photosensitivity and a predisposition to skin cancer on sun-exposed areas of the body. The primary defect in XP involves nucleotide excision repair (NER) (summary by Flejter et al., 1992). Clinical Features In a 31-year-old patient with XP classified as complementation group D by cell-fusion complementation methods, Ichihashi et al. (1988) described mild skin lesions and no apparent neurologic abnormalities despite the characteristic group D level of DNA repair deficiency. Johnson and Squires (1992) stated that more than 30 unrelated individuals with XPD were known and that less than half of them showed major abnormalities of the central nervous system, once considered to be the hallmark of XPD.
A number sign (#) is used with this entry because xeroderma pigmentosum complementation group A (XPA) is caused by homozygous or compound heterozygous mutation in the XPA gene (611153) on chromosome 9q22. Description Xeroderma pigmentosum is a genetically heterogeneous autosomal recessive disorder characterized by increased sensitivity to sunlight with the development of carcinomas at an early age. Some patients develop neurologic symptoms or a more severe clinical phenotype known as de Sanctis-Cacchione syndrome (278800) (Satokata et al., 1992). See also XPB (610651), XPC (278720), XPD (278730), XPE (278740), XPF (278760), XPG (278780), and variant XP (XPV; 278750). Clinical Features Ruder (cited by Cockayne, 1933) observed the condition in 7 out of 13 sibs.
Clinical Features In addition to the usual severe, recessively inherited xeroderma pigmentosum (278700-278780), the existence of a milder form behaving as a dominant was claimed by Anderson and Begg (1950) who described 11 affected persons in 5 sibships of 4 generations of a Scottish family by the name of MacPherson. The patients showed freckling and multiple skin cancers as in the recessive form but did not get into trouble as early in life and survived longer. Indeed, Anderson and Begg examined 1 affected member of the family who was 74 years of age. No affected member was said to have died of the disease. Sedano (1984) raised doubts about this family. In the Scottish family, Anderson personally examined 7 members: 'Mr. George MacPherson, sen., his wife, George, jun., Harold, Lena, Douglas, and the son of George, jun.
Xeroderma pigmentosum (XP) is a rare genodermatosis characterized by extreme sensitivity to ultraviolet (UV)-induced changes in the skin and eyes, and multiple skin cancers. It is subdivided into 8 complementation groups, according to the affected gene: classical XP (XPA to XPG) and XP variant (XPV) (see these terms). Epidemiology It has an estimated prevalence of 1/1,000,000 in the USA and Europe, with higher figures in other countries (e.g. Japan, North Africa and Pakistan), particularly in communities with a high degree of consanguinity. Clinical description The severity of the clinical manifestations and the age of onset are extremely variable and are in part dependent on exposure to sunlight and the complementation group.
Xeroderma pigmentosum (XP) causes the skin and eyes to be extra sensitive to exposure to ultraviolet radiation from the sun and other sources. Symptoms begin in early childhood. People with XP can develop bad sunburns, blistering, and freckling in response to sunlight. The eyes may develop light sensitivity, corneal clouding, and swelling. Some people with XP have nervous system involvement as well. People with XP are at very high risk of developing skin cancer and other types of cancers. XP is caused by variants in one of at least nine genes involved in repairing damaged DNA.
A number sign (#) is used with this entry because xeroderma pigmentosum complementation group C (XPC) is caused by mutation in the XPC gene (613208) on chromosome 3p25. Description Xeroderma pigmentosum is a genetically heterogeneous condition characterized by increased sensitivity to ultraviolet (UV) irradiation and increased risk of skin cancer resulting from a defect in DNA repair. XPC is the most common form of XP in the white population, accounting for over a third of all cases in this group (review by Li et al., 1993). For a general discussion of xeroderma pigmentosum, see XPA (278700). Clinical Features Lynch et al. (1984) suggested that complementation group C patients may be particularly prone to malignant melanoma. Li et al. (1993) identified 2 patients with XPC confirmed by genetic analysis (613208.0003).
A number sign (#) is used with this entry because the phenotype associated with xeroderma pigmentosum complementation group B (XPB) is caused by mutation in the DNA excision repair gene ERCC3 (133510) on chromosome 2q14. Description For a general discussion of xeroderma pigmentosum, see XPA (278700), and of Cockayne syndrome, see CSA (216400). Cleaver (1990) provided a review of the causes of xeroderma pigmentosum. Clinical Features Lehmann (1982) performed cell fusion studies on cultured cells from 11 patients with Cockayne syndrome. The 11 cell lines were assigned to 3 complementation groups: 2 to group A, 8 to group B, and 1 to group C.
A number sign (#) is used with this entry because of evidence that the disorder is caused by homozygous or compound heterozygous mutation in the ERCC4 gene (133520) on chromosome 16p13. Description Xeroderma pigmentosum is an autosomal recessive disorder characterized by sun sensitivity and increased skin sensitivity to UV light, as well as an increased risk of skin cancer associated with a defect in nucleotide excision repair (NER). The XPF form of XP is usually relatively mild compared to other forms. Patients with XPF tend to have later onset of skin cancer. Some patients with XPF may develop neurologic impairment or growth defects, and are then classified as having Cockayne syndrome (summary by Kashiyama et al., 2013). For a general phenotypic description and a discussion of genetic heterogeneity of xeroderma pigmentosa, see XPA (278700), and of Cockayne syndrome, see CSA (216400).
A number sign (#) is used with this entry because xeroderma pigmentosum complementation group E is caused by homozygous mutation in the DDB2 gene (600811) on chromosome 11p11. For background information on xeroderma pigmentosum, see 278700. Clinical Features Kondo et al. (1988) studied 3 Japanese patients, aged 50, 42, and 41 years, with mild XP symptoms and no neurologic abnormalities. Two had developed basal cell carcinomas at ages 46 and 41 years. Chu and Chang (1988) studied cells from 2 second-cousin patients with group E xeroderma pigmentosum who had a skin disease less severe than that seen in patients of several other complementation groups (de Weerd-Kastelein et al., 1974). Using an extension of the gel electrophoresis binding assay, Chu and Chang (1988) identified at least 1 nuclear factor that binds to DNA damaged by ultraviolet radiation or the antitumor drug cisplatin, but is notably absent in group E cells. The defect was not the result of a failure of protein transport to the nucleus since binding activity was absent in both the nuclear and cytoplasmic extracts.

Description Autoimmune thrombocytopenic purpura is characterized by a low platelet count, normal bone marrow, and the absence of other causes of thrombocytopenia. It is principally a disorder of increased platelet destruction mediated by autoantibodies to platelet-membrane antigens (George et al., 1994). Clinical Features In children, AITP is usually acute and self-limited, whereas in adults, it is most often chronic. The presenting features are bruising, petechiae, and/or mucosal bleeding (epistaxis, hematuria, and rarely intracerebral hemorrhage) (George et al., 1994). Cines and Blanchette (2002) and Imbach et al. (2002) provided comprehensive reviews.
Immune thrombocytopenia is a disorder characterized by a blood abnormality called thrombocytopenia, which is a shortage of blood cells called platelets that are needed for normal blood clotting. Affected individuals can develop red or purple spots on the skin caused by bleeding just under the skin's surface. Small spots of bleeding under the skin are called purpura and larger spots are called ecchymoses. People with immune thrombocytopenia can have significant bleeding episodes, such as nose bleeds (epistaxis) or bleeding in the moist lining (mucosae) of the mouth. In severe cases, individuals may have gastrointestinal bleeding or blood in the urine or stool, or heavy and prolonged menstrual bleeding (menorrhagia).
A rare autoimmune coagulation disorder characterized by isolated thrombocytopenia (a platelet count <100,000/microL), in the absence of any underlying disorder that may be associated with thrombocytopenia. Epidemiology The annual incidence is estimated at between 1/25,600-37,000 in Europe, with a female to male ratio of 1.3:1. Although immune thrombocytopenia (ITP) can occur at any age, incidence shows an age-specific bimodal distribution for men with two incidence peaks observed in boys (under 18 years old) and among those older than 60 years of age. Clinical description ITP exposes to a risk of bleeding. It is defined as severe when the presence of bleeding symptoms at presentation is sufficient to warrant treatment or when the occurrence of new bleeding symptoms requires additional therapeutic intervention. It is asymptomatic in one-third of cases. Mucocutaneous hemorrhage with purpura is the most frequent clinical manifestation, usually occurring when the platelet count is below 30,000/microL.
Idiopathic thrombocytopenic purpura (ITP) is a bleeding disorder characterized by too few platelets in the blood. This is because platelets are being destroyed by the immune system. Symptoms may include bruising, nosebleed or bleeding in the mouth, bleeding into the skin, and abnormally heavy menstruation . With treatment, the chance of remission (a symptom-free period) is good. Rarely, ITP may become a chronic ailment in adults and reappear, even after remission.
A rare acute myeloid leukemia that occurs predominantly in childhood and particularly in children with Down syndrome (DS-AMKL). Nonspecific symptoms may be irritability, weakness, and dizziness while specific symptoms include pallor, fever, mucocutaneous bleeding, hepatosplenomegaly, neurological manifestations and rarely lymphadenopathy. Acute panmyelosis with myelofibrosis may also be associated with AMKL. In contrast to DS-AMKL (around 80 % survival), non-DS-AMKL is an AML subgroup associated with poor prognosis.
Summary Clinical characteristics. Autosomal dominant polycystic kidney disease (ADPKD) is generally a late-onset multisystem disorder characterized by bilateral renal cysts, liver cysts, and an increased risk of intracranial aneurysms. Other manifestations include: cysts in the pancreas, seminal vesicles, and arachnoid membrane; dilatation of the aortic root and dissection of the thoracic aorta; mitral valve prolapse; and abdominal wall hernias. Renal manifestations include hypertension, renal pain, and renal insufficiency. Approximately 50% of individuals with ADPKD have end-stage renal disease (ESRD) by age 60 years. The prevalence of liver cysts increases with age and occasionally results in clinically significant severe polycystic liver disease (PLD).

Acute disseminated encephalomyelitis (ADEM) is a neurological condition characterized by a brief but intense attack of inflammation in the brain and spinal cord. This may lead to damage of the layer of insulation around the nerves (myelin) within affected areas. ADEM often follows viral infection, or less often, vaccinations for measles, mumps, or rubella (MMR). Symptoms usually appear rapidly, beginning with fever, fatigue, headache, nausea and vomiting. Treatment for ADEM is targeted at suppressing inflammation in the brain using anti-inflammatory drugs.
A demyelinating disorder of the central nervous system. Epidemiology The incidence rate has been estimated at 1 in 125,000-250,000 per year. Clinical description Children younger than 10 years are predominantly affected. A seasonal winter and spring peaks have been registered. The disease usually develops after acute viral or bacterial infection or vaccination, with a sudden onset of irritability and lethargy after a prodromal period of 1-4 weeks. Major symptoms include fever, headache, drowsiness, changes in mental status, seizures and coma. Weakness, vomiting, weight loss, stiff neck, ataxia, bilateral optic neuritis and delirium are common.
