Research Abstract

For GWAS, 372 Japanese NAFLD subjects and 934 control individuals were analyzed. For replication studies, 172 NAFLD and 1012 control subjects were monitored. Rs738409 in the PNPLA3 gene was most strongly associated with NAFLD. Rs2896019, and rs381062 in the PNPLA3 gene, rs738491, rs3761472, and rs2143571 in the SAMM50 gene, rs6006473, rs5764455, and rs6006611 in the PARVB gene had also significant and were associated with decreased serum triglycerides and increased AST and ALT in NAFLD patients. These SNPs were associated with steatosis grade and NAS. Rs738409, rs2896019, rs738491, rs6006473, rs5764455, and rs6006611 were associated with fibrosis. We amplified approximately 150kb region including PNPLA3 of 19 NAFLD and 9 control subjects and analyzed by next-generation sequencing.
