Genetic Variants in the SAMM50 Gene Create Susceptibility to Nonalcoholic Fatty Liver Disease in a Chinese Han Population

Conclusions: We first demonstrated that the rs738491 T allele, rs2143571 A allele, and rs3761472 G allele in the SAMM50 gene created susceptibility to NAFLD in a Chinese Han population. The combination of the three SNPs in the SAMM50 gene may have synergism to predict the predisposition to NAFLD.,Background: Genome-wide association studies have shown that rs738491, rs2143571, and rs3761472 in the sorting and assembly machinery component 50 homolog (SAMM50) gene are significantly associated with susceptibility to nonalcoholic fatty liver disease (NAFLD).,Objectives: The present study evaluated the association between the three genetic variants in the SAMM50 gene and susceptibility to NAFLD in a Chinese Han population.,Patients and Methods: Genotypes for 3 single nucleotide polymorphisms (SNPs), viz rs738491, rs2143571, and rs3761472, in the SAMM50 gene were determined using an improved multiplex ligation detection reaction technique in 340 B-type ultrasonography-diagnosed NAFLD patients and 452 healthy controls. Meanwhile, serum lipid profiles and liver enzymes were estimated using standard clinical laboratory methods. The SNP-SNP interactions were analyzed by performing multifactor dimensionality reduction (MDR) and generalized multifactor dimensionality reduction (GMDR).,Results: The genotype and allele frequencies of the SAMM50 polymorphisms between the NAFLD group and the control group were significantly different (all Ps < 0.05). In the multivariate analysis adjusted f...
