[Studies on the relationship between D6S1581, a high frequency allele imbalance locus, and genetic susceptibility to nasopharyngeal carcinoma].

OBJECTIVE:To investigate the relationship of nasopharyngeal carcinoma (NPC) with the high frequency allele imbalance locus D6S1581, and the NPC associated gene FBXO30 which is located near D6S1581. METHODS:Genescan was used to genotype D6S1581 of 12 NPC pedigrees, 85 sporadic NPC patients and 181 normal volunteers. Then parametric/nonparametric linkage analysis and association analysis were performed. RESULTS:D6S1581 was linked with NPC, a Lod score of 2.611436 (P=0.00245) was obtained, and a significant difference in allele frequency was observed between familial NPC and control (P<0.005). CONCLUSION:These results suggest that D6S1581 is highly associated with NPC, and there may be one or more NPC associated genes near D6S1581, including FBXO30.
