OBJECTIVE: To investigate the relationship between MKKS gene variations, obesity-related traits and features of the metabolic syndrome (MS) in the Greek population. DESIGN AND SUBJECTS: Genotype and haplotype analysis was carried out for six known MKKS gene polymorphisms (534C>T, 985+16T>G, 985+33C>G, 986-29A>T, 1161+58A>G and 1595G>T) in 220 obese subjects (body mass index > or =30 kg/m(2)) and 330 non-obese controls. RESULTS: Genotype frequencies of the 985+16T>G, 986-29A>T and 1595G>T SNPs were significantly different between obese and non-obese individuals (P=0.0016, 0.0196 and 0.0069, respectively). Obese carriers of the risk alleles of the above three polymorphisms had a significantly increased prevalence of arterial hypertension. Furthermore, obese carriers of the G allele for the 985+16T>G polymorphism had an increased prevalence of type 2 diabetes mellitus and of MS component traits. A new polymorphism was detected, namely a C to T substitution at position 1129 (1129C>T or N377N). Frequency of the T allele for the 1129C>T polymorphism was significantly higher in control individuals than in obese subjects (P=0.0253). Haplotype TGTGT was more prevalent in obese than in controls (P=0.0002) and was associated with increased prevalence of the MS in obese subjects (P<0.0001). CONCLUSION: Our results suggest that genetic variation in the MKKS gene may play a role in the development of obesity and the metabolic syndrome.
