Abstract

Genetic heterogeneity is a difficulty frequently encountered in the search for genes conferring susceptibility to prostate cancer. To circumvent this issue, we selected a large prostate cancer pedigree for genome-wide linkage analysis from a population that is genetically homogeneous. Selected cases and first-degree relatives were genotyped with Affymetrix 10K SNP arrays, identifying a 14 Mb haplotype on chromosome 5 (5p13-q12) inherited identical-by-descent (IBD) by multiple cases. Microsatellite genotyping of additional deceased case samples confirmed that a total of eight cases inherited the common haplotype (P=0.0017). Re-sequencing of eight prioritised candidate genes in the region in s..
