Leptin G-2548A and leptin receptor Q223R gene polymorphisms are not associated with obesity in Romanian subjects.

We aimed to investigate whether polymorphisms LEP G-2548A and LEPR Q223R in the human leptin (LEP), and leptin receptor (LEPR) genes are associated with obesity and metabolic traits in a sample of Romanian population. Two hundred and two subjects divided in obese (body mass index, BMI30 kg/m(2)), and non-obese were included in this study. The polymorphisms were genotyped using polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP) analysis.
