Introduction: There are many factors responsible for the development of metabolic syndrome – mainly associated with lifestyle, but also genetic ones. MC4R (melanocortin 4 receptor) genes variants have been associated with the risk of developing obesity, type 2 diabetes mellitus and coronary artery disease.

Aim of the study: To investigate the association between MC4R rs17782313 polymorphism and concentrations of glucose, insulin, HOMA-IR and QUICKI values in the whole study group.

Materials and methods: Study group consisted of 294 patients (136 men and 158 women). Collected venous blood samples were stored at -700C until the study group was completed. In the laboratory of Clinical Hospital 1 in Zabrze, the DNA materials were isolated, proper concentration of the DNA (15 ng/μL) were prepared and quality and quantity were checked by spectrophotometry. Allelic discrimination was performed with the use of fluorescent-labelled TaqMan Pre-designed SNP Genotyping Assay probes.

Results: No statistically significant differences in concentrations of cholesterol, HDL, LDL, TG between genotypes in women and men were observed. In the whole group of patients, glucose and insulin levels did not differ significantly between TT, CT and CC carriers. Significant differences in values of HOMA-IR and QUICKI between TT, CT and CC carriers as well as between TT carriers and CT+CC carriers were found. CC+TT carriers have a significantly lower value of HOMA-IR and higher QUICKI value than TT carriers.

Conclusions: MC4R polymorphism in rs17782313 may be associated with insulin resistance. Further studies are necessary to completely assess the association between investigated polymorphism, insulin resistance and risk of diabetes mellitus development.
