Genome-wide scan for familial nasopharyngeal carcinoma reveals evidence of linkage to chromosome 4
，-0001，（）：
Nasopharyngeal carcinoma (NPC) occurs with high frequency in Asian populations, especially among people of Cantonese ancestry. In areas with high incidence, NPC clusters in families, which suggests that both geography and genetics may influence disease risk1-6. Although the HLA-Bw46 locus is associated with increased risk of NPC7,8, no predisposing genes have been identified so far. Here we report the results of a genome-wide search carried out in families at high risk of NPC from Guangdong Province, China. Parametric analyses provide evidence of linkage to the D4S405 marker on chromosome 4 with a logarithm of odds for linkage (Iod) score of 3.06 and a heterogeneity-adjusted Iod (hlod) score of 3.21. Fine mapping with additional markers flanking D4S405 resulted in a lod score of 3.54 and hlod score of 3.67 for the region 4p15.1-q12. Multipoint nonparametric linkage analysis gives Iod scores of 3.54 at D4S405 (P=5.4
