Genetic Polymorphisms of PNPLA3 and SAMM50 Are Associated with Nonalcoholic Fatty Liver Disease in a Korean Population.

ABSTRACT:

Background/aims

The development of nonalcoholic fatty liver disease (NAFLD) is associated with multiple genetic and environmental factors.

Methods

We performed a genome-wide association study to identify the genetic factors related to NAFLD in a Korean population-based sample of 1,593 subjects with NAFLD and 2,816 controls. We replicated the data in another sample that included 744 NAFLD patients and 1,137 controls. We investigated single-nucleotide polymorphisms (SNPs) that were related to NAFLD.

Results

After adjusting for age, sex and body mass index, rs738409, rs12483959 and rs2281135, located in the PNPLA3 gene, were validated in our population (p＜8.56×10^-8) in the same linkage disequilibrium block. Additionally, rs2143571, rs3761472, and rs2073
