GPT and metabolic dysfunction-associated steatotic liver disease: Another genetic risk variant (rs72613567:TA in HSD17B13 encoding the hepatic lipid droplet protein hydroxysteroid 17-beta dehydrogenase 13) could also be involved in NAFLD and ALD [70,232] with reduced levels of ALT and AST, reduced risk of ALD (by 42% among heterozygotes and by 53% among homozygotes), NAFLD (by 17% among heterozygotes and by 30% among homozygotes), alcoholic cirrhosis (by 42% among heterozygotes and by 73% among homozygotes), and nonalcoholic cirrhosis (by 26% among heterozygotes and by 49% among homozygotes) [232].
