PNPLA3 and cryohydrocytosis: After determining haplotype frequencies, we evaluated the associations between the two PNPLA3-identified haplotypes and serum liver damage markers (AST, ALT, GGT, and platelet counts) and noninvasive liver damage indices (APRI levels, FIB-4, HIS, and liver stiffness) in SC and CHC patients.
