Leukemia, Chronic Lymphocytic, Susceptibility To, 1
For a phenotypic description and a discussion of genetic heterogeneity of chronic lymphocytic leukemia (CLL), see 151400.
MappingTo identify a susceptibility gene for CLL, Sellick et al. (2005) conducted a genomewide linkage analysis of 115 pedigrees using a high density single-nucleotide polymorphism (SNP) array. They obtained a maximum nonparametric linkage score (NPL) of 3.14 (P = 0.0008) on 11p11. The same genomic position yielded the highest multipoint heterogeneity lod score under both dominant and recessive models. In addition, 4 other chromosomal positions (5q22-q23, 6p22, 10q25, and 14q32) displayed multipoint heterogeneity lod scores greater than 1.15. None of the regions coincided with areas of common chromosomal aberrations frequently observed in CLL.
