In both HS and CHB+HS group, hepatic steatosis patients bearing CC and TC genotypes of PNPLA3 rs1010023 were susceptible to decreased level of FBG in comparison to those with TT genotype (CC/TC versus TT: 4.81 ± 0.92 mmol/L versus 5.86 ± 2.11 mmol/L (CHB+HS group), P = 0.017; 4.27 ± 0.82 mmol/L versus 5.52 ± 1.11 mmol/L (HS group), P = 0.003) (Table 5). Here, PNPLA3 is linked to fatty liver disease.
