Obesity is a disease characterized by excessive body fat. Among the neurobiological factors associated with obesity, the serotonergic system stands out. The neurotransmitter of these circuits is serotonin (5-HT). Decreased levels of 5-HT have been linked to increased desire to ingest sweets and carbohydrates. This study aims to verify the relationship of the 5HT2A T102C gene polymorphism with obesity and anthropometric parameters. Blood samples and anthropometric data were collected from 150 volunteers, divided between the control and obese groups. The results showed that for individuals with diastolic pressure (p = 0.3681), Estimated Mean Glycemia (GMe) (p = 0.0228) and Homeostatic Model Assessment (HOMA-IR-IR) (p = 0.001) all altered, a higher frequency of C alleles was observed. For normal GMe (p = 0.0270), a higher frequency of the T allele was observed. There was no difference for the allele distribution between the normal and altered groups for the parameters of Triglycerides, HDL cholesterol, total cholesterol, glycated hemoglobin and Insulin. The distribution of the alleles between the groups, normal diastolic pressure (p = 0.3681) and HOMA-IR (p = 0.9203) groups presented no difference. From the genotypic analyzes of the T102C polymorphism of the 5HT2A gene, it was possible to demonstrate a relationship between the presence of the C allele with biochemical and anthropometric markers related to obesity and hypertension.
