Bardet-Biedl syndrome (BBS) is a rare developmental disorder with the cardinal features of abdominal obesity, retinopathy, polydactyly, cognitive impairment, renal and cardiac anomalies, hypertension, and diabetes. BBS is genetically heterogeneous, with nine genes identified to date and evidence for additional loci. In this study, we performed mutation analysis of the coding and conserved regions of BBS1, BBS2, BBS4, and BBS6 in 48 French Caucasian individuals. Among the 36 variants identified, 12 were selected and genotyped in 1,943 French-Caucasian case subjects and 1,299 French-Caucasian nonobese nondiabetic control subjects. Variants in BBS2, BBS4, and BBS6 showed evidence of association with common obesity in an age-dependent manner, the BBS2 single nucleotide polymorphism (SNP) being associated with common adult obesity (P = 0.0005) and the BBS4 and BBS6 SNPs being associated with common early-onset childhood obesity (P = 0.0003) and common adult morbid obesity (0.0003 < P < 0.007). The association of the BBS4 rs7178130 variant was found to be supported by transmission disequilibrium testing (P = 0.006). The BBS6 variants also showed nominal evidence of association with quantitative components of the metabolic syndrome (e.g., dyslipidemia, hyperglycemia), a complication previously described in BBS patients. In summary, our preliminary data suggest that variations at BBS genes are associated with risk of common obesity.

Genetic factors are important in the development of metabolic syndrome. However, the genetic background of metabolic syndrome remains unclear. We screened polymorphisms in 85 obesity-related genes to determine which may be associated with metabolic syndrome. A total of 336 single-nucleotide polymorphisms (SNPs) in 85 genes selected from the JSNP database were genotyped. We conducted case-control association analyses using patients with metabolic syndrome (n=1080) and control individuals (n=528) who had no risk of the metabolic syndrome. Three SNPs in the McKusick-Kaufman syndrome (MKKS) gene were significantly related to metabolic syndrome by case-control association study; rs1545 (odds ratio (OR) adjusted for age and gender, 1.45; 95% confidence interval (CI), 1.21-1.74; P=0.000043 (additive model)); rs1547 (OR, 1.45; 95% CI, 1.21-1.74; P=0.000041); and rs2294901 (OR, 1.46; 95% CI, 1.22-1.75; P=0.000033). We selected five tag SNPs (rs2294901, rs221667, rs6133922, rs6077785 and rs6108572) in the MKKS gene. They were in one linkage disequilibrium (LD) block and rs6133922 (P=0.00042), rs6077785 (P=0.000013) and rs6108572 (P=0.000019) as well as rs2294901 were significantly associated with metabolic syndrome. TGAAA haplotype was protective against the metabolic syndrome (P=0.0074), and CCGTT haplotype was susceptible (P=0.00070) to the metabolic syndrome. Our data suggest that genetic variations at MKKS gene influence the risk of metabolic syndrome.
