The variability of PNPLA3 gene as a potential marker of cold adaptation in Yakuts.

Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases. It has been reported that specific variants of patatin-like phospholipase domain-containing 3 (PNPLA3) gene, notably SNPs rs738409 and rs2294918 are associated with high risks of liver disease. PNPLA3 rs738409 polymorphism is the main determinant of fatty liver and affects development and progression of NAFLD.
