ABSTRACT Objective: Metabolic dysfunction-associated steatotic liver disease (MASLD), a worldwide public health challenge with a prevalence of around 25%, is strongly related to obesity and insulin resistance. The present study investigated the possible association between MASLD and the leptin gene (LEP) -2548G>A (rs7799039) polymorphism. Subjects and methods: A total of 250 subjects (125 biopsy-proven MASLD patients and 125 controls) were genotyped for the -2548G>A promoter variant using the PCR-RFLP technique. Results: There was no deviation from Hardy-Weinberg equilibrium for LEP […]
