Core Tip Epigenetic dysregulation of leptin (LEP) gene in lean Chinese patients with diabetes has been understudied. Sun et al performed a cross-sectional study to investigate the associations of LEP promoter methylation levels and serum leptin concentrations with diabetes progression in non-obese individuals (body mass index < 24 kg/m²). Findings indicated that in lean adult Chinese patients (body mass index < 24 kg/m²), the methylation of the LEP promoter gradually decreased during the progression of diabetes, demonstrating a significant inverse correlation with serum leptin levels. These findings imply that LEP promoter methylation may act as a potential biomarker for early risk stratification of diabetes and prediction of its severity in non-obese patients with diabetes.
