  • Bosma Arhinia Microphthalmia Syndrome OMIM
    The authors stated that this was the fifteenth reported case of BAMS, and the first reported Mexican case. Brasseur et al. (2016) studied a man in his forties who was born with arhinia, choanal atresia, bilateral microphthalmia with coloboma, and hypogonadotropic hypogonadism. ... Of 31 assessable subjects (22 male and 9 female), 97% demonstrated hypogonadotropic hypogonadism (HH), and the 7 subjects for whom brain MRI data were available had no olfactory structures. Molecular Genetics By whole-genome, whole-exome, and targeted sequencing in 38 probands with arhinia, Shaw et al. (2017) identified heterozygous missense mutations in the SMCHD1 gene in 32 (84%) of the probands, including patients previously reported by Gifford et al. (1972), Ruprecht and Majewski (1978), Bosma et al. (1981), Muhlbauer et al. (1993), Thiele et al. (1996), Olsen et al. (2001), Graham and Lee (2006), Tryggestad et al. (2013), Becerra-Solano et al.

    • Burn-Mckeown Syndrome MedlinePlus
      Burn-McKeown syndrome is a disorder that is present from birth (congenital) and involves abnormalities of the nasal passages, characteristic facial features, hearing loss, heart abnormalities, and short stature. In people with Burn-McKeown syndrome, both nasal passages are usually narrowed (bilateral choanal stenosis) or completely blocked (bilateral choanal atresia), which can cause life-threatening breathing problems in infancy without surgical repair. Typical facial features include narrow openings of the eyelids (short palpebral fissures ); a gap (coloboma) in the lower eyelids; widely spaced eyes (hypertelorism); a prominent bridge of the nose; a short space between the nose and the upper lip (philtrum); a small opening of the mouth (microstomia); and large, protruding ears . Some people with Burn-McKeown syndrome have congenital hearing loss in both ears which varies in severity among affected individuals. The hearing loss is described as mixed, which means that it is caused by both changes in the inner ear (sensorineural hearing loss) and changes in the middle ear (conductive hearing loss).

      Klippel-Trenaunay syndrome (KTS) is a syndrome that affects the development of blood vessels, soft tissues, and bones. This syndrome has three characteristic features: a red birthmark called a port-wine stain , overgrowth of soft tissues and bones, and vein malformations such as varicose veins or malformations of deep veins in the limbs. The overgrowth of bones and soft tissues usually begins in infancy and is most often only affects one leg. However, it can also affect the arms or sometimes the upper body area (torso). The overgrowth can cause pain, a feeling of heaviness, and make the affected leg (or arm) hard to move.

      Overview Klippel-Trenaunay (klih-PEL tray-no-NAY) syndrome ― also called KTS ― is a rare disorder found at birth (congenital) involving problems in the development of certain blood vessels, soft tissues (such as skin and muscles), bones and sometimes the lymphatic system. The main features include a red birthmark (port-wine stain), ranging in color from pink to reddish-purple, atypical vein or lymphatic development (malformations), and overgrowth of tissues and bones. These findings most often affect one leg but may occur in an arm or elsewhere. Although there is no cure for KTS , treatment goals are to improve symptoms and prevent complications. Symptoms People who have KTS may have the following features, which can range from mild to more extensive: Port-wine stain.
