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.
- genetic susceptibility
- cancer predisposition
- familiar cancer
- homogeneous population
