For the F0-F1 classification of fibrosis, individuals with the ArgValAlaAla+/+ haplotype had high VLs but low levels of liver enzymes compared to the heterozygous (VL - p: 0.0473) and homozygous ArgValValAla+/+ haplotypes (ALT - p: 0.0307; AST - p: 0.0179; GGT - p: 0.0172). The gene discussed is GPT; the disease is fibrosis.
