Abstract
Chromosome 4q is one of the most common regions with a high frequency of allelic loss in hepatocellular carcinoma (HCC). To identify the HCC-susceptibility locus on chromosome 4q, we have performed linkage and family-based association analyses on Chinese families with HCC from Taiwan, where hepatitis B is hyperendemic. Using 77 microsatellite markers spanning chromosome 4q on 52 multiplex families, we found suggestive evidence of linkage to 4q22.3-28.1 with a maximum two-point heterogeneity LOD (HLOD) score of 2.55 at marker D4S3240 on chromosome 4q25. Multipoint analyses with microsatellite markers in the region 4q22.3-28.1 resulted in a maximum HLOD score of 3.12 and a maximum nonparametric linkage (NPL) Z score of 1.98 (pointwise P=0.0080; region-wide empirical P=0.021) for D4S3240. The evidence for linkage to D4S3240 was seen mostly in a subset of 28 families lacking affected parents, which showed multipoint HLOD and NPL scores of 3.25 and 2.79 (pointwise P=0.0028; region-wide empirical P=0.008), respectively. Family-based association analyses of the 77 microsatellite markers in 191 families (53 multiplex plus 138 singleton families) using the pedigree disequilibrium test provide further support for observed linkage. Additional genotyping in the 52 multiplex families informative for linkage analyses was performed for 29 single-nucleotide polymorphisms around D4S3240. A common haplotype (at markers rs7442180 and rs221330) positioned ?873 kb away from D4S3240 was associated with HCC, with P=0.0074. ? 2006 Nature Publishing Group All rights reserved.
