Single-nucleotide polymorphism genotyping for C282Y (rs1800562) and H63D (rs1799945) HFE mutations was performed in 786 adult subjects in the NASH Clinical Research Network (CRN).
Sex (63-67% male) and age at diagnosis of NASH did not differ between those with or without HFE mutations, but men with NASH were significantly more likely than women to have the H63D mutation (15/23 vs. 3/13, p<0.05) Levels of serum ferritin, iron, transferrin saturation levels, and the degree of hepatic iron staining were significantly higher (p<0.05) in subjects with NASH who carried an HFE mutation than in those without.
