Abstract
Obesity is an important risk factor of Obstructive Sleep Apnea Syndrome (OSAS). Previous studies suggested
Leptin Receptor (LEPR) gene Polymorphisms is associated with obesity and OSAS. Study was conducted
to asses association of LEPR gene polymorphism K109R, Q223R and K656N with OSAS in North Indian
subjects. Genotyping and estimation of serum Leptin levels were done in 190 subjects. Polysomnography,
anthropometrical measures and biochemical investigations were done in all the subjects who qualified for
inclusion in the study. We observed significant association of Q223R gene polymorphism with blood pressure
(BP) (P<0.05) and nocturnal max pulse rate (P<0.05). K656N gene polymorphism was associated with AHI
(P<0.05), average desaturation levels (P<0.05) and HDL-C (P<0.05). No association was observed in genotype
distribution of these subjects according to obesity and disease severity. These findings suggest that LEPR
Q223R and K656N gene Polymorphism may influence BP, Max Pulse rate, AHI, Average desaturation levels
and HDL levels in these Subjects.
