Abstract

BACKGROUND: In order to identify predisposition loci to hereditary prostate cancer (HPC), we performed a genome-wide linkage analysis using samples from a genetically homogeneous population, with 13 Finnish multiplex prostate cancer families.

METHODS: Altogether 87 DNA samples were genotyped from 13 families. Logarithm-of-odds (LOD) scores were calculated for all autosomes using FASTLINK and GENEHUNTER designating all unaffected men and all women as unknown.

RESULTS: The highest LOD scores in the affected-only analyses were found at 11q14, where the two-point LOD score was 2.97 (θ = 0.0 at D11S901), GENEHUNTER heterogeneity LOD (HLOD) of 3.36, and a non-parametric-linkage (NPL) score of 2.67 (P = 0.008). A second positive site was at 3p25‐26, with a two-point LOD score of 2.57 (θ = 0.01 at D3S1297), HLOD of 2.15, and NPL score of 2.27 (P = 0.02).

CONCLUSIONS: The results suggest two HPC regions in the Finnish population, which have not been reported previously and warrant further study.
