Abstract
© FUNPEC-RP. Genetic variants of the POMC and PCSK1 genes cause severe obesity among patients in the early stages of childhood. This family-based study analyzed the links between single nucleotide polymorphisms (SNPs) in either the POMC or PCSK1 genes and obesity, as well as obesity-related traits among obese Thai children and their families. The variants rs1042571 and rs6713532 in the POMC gene in a sample of 83 obese children and their family members were investigated using polymerase chain reaction (PCR)-restriction fragment length polymorphism. In addition, the SNPs rs6232, rs155971, rs3762986, rs3811942, and rs371897784 of PCSK1 were analyzed in all samples using PCR and gene sequencing methods. Participants with the homozygous variant genotype in rs155971 had significantly elevated cholesterol and low-density lipoprotein cholesterol (LDL-C) levels (P = 0.011, OR = 1.025, 95%CI = 1.006-1.045; and P = 0.006, OR = 1.030, 95%CI = 1.009-1.053, respectively) after adjustment for age, gender, and body mass index (BMI). In addition, patients with the heterozygous variant genotype in rs371897784 of PCSK1 had a 1.249- fold higher risk (95%CI = 1.081-1.444, P = 0.027) of increased waist circumference than patients with the normal genotype, after adjustment for age, gender, and BMI. However, this analysis did not find any correlation between obesity and SNPs in PCSK1 and POMC. Therefore, these common variants in PCSK1 and POMC were not the major cause of obesity in the Thai subjects sampled. However, variants in PCSK1 did affect cholesterol level, LDL-C level, and waist circumference.
