Evidence for a prostate cancer-susceptibility locus on chromosome 20.

ABSTRACT: Recent studies suggest that hereditary prostate cancer is a complex disease involving multiple susceptibility genes and variable phenotypic expression. While conducting a genomewide search on 162 North American families with > or =3 members affected with prostate cancer (PRCA), we found evidence for linkage to chromosome 20q13 with two-point parametric LOD scores >1 at multiple sites, with the highest two-point LOD score of 2.69 for marker D20S196. The maximum multipoint NPL score for the entire data set was 3.02 (P=.002) at D20S887. On the basis of findings from previous reports, families were stratified by the presence (n=116) or absence (n=46) of male-to-male transmission, average age of diagnosis (<66 years, n=73; > or =66 years, n=89), and number of affected individuals (<5, n=101; >
