Abstract:
In this study, we report the association of the rs738407, rs738409, and rs2896019 variants of the patatin-like phospholipase domain-containing protein 3 (PNPLA3) (adiponutrin) gene with nonalcoholic steatohepatitis (NASH) (χ(2)=14.528, p=0.001; χ(2)=18.882, p=0.000; χ(2)=7.449, p=0.024, respectively) in 80 patients with NASH and 303 healthy controls. We genotyped the subjects using three polymerase chain reaction-restriction fragment length polymorphism methods developed in our laboratory. Our findings confirm the findings of the recent case-control and genome-wide association studies carried out in different populations around the world. Thus, the three variants in PNPLA3 gene may be a genetic risk factor for NASH.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
