Genotyping of <jats:italic>PNPLA3</jats:italic>, <jats:italic>TM6SF2</jats:italic>, and <jats:italic>HSD17B13</jats:italic> was undertaken, and the combined GRS was calculated. The relationship between the GRS and the incidence of posttransplant SLD was also evaluated.ResultsThe SLD recipients had a high prevalence of post‐LT graft steatosis/steatohepatitis (76.4% and 58.2%, respectively). Although the recipients had a high frequency of risk alleles, there was no relationship between the number of risk alleles for each SNP and the incidence of posttransplant SLD. In contrast, an increased number of risk alleles for any SNP in the donor was correlated with high incidence rates of both post‐LT steatosis and steatohepatitis. A multivariable analysis showed that a high donor GRS was an independent risk factor for graft steatosis (odds ratio 8.77; 95% CI, 1.94–52.94; <jats:italic>p</jats:italic> = 0.009).
