Introduction and aim. Dysfunction of the glucagon-like peptide 1 (GLP-1)/GLP-1 receptor (GLP-1R) axis promotes obesity and metabolic disorders. The aim was to study the associations of the single nucleotide variants (SNV) GLP1R gene with proinflammatory cytokines and metabolic disorders in children with various obesity phenotypes. Material and methods. 252 children with obesity aged 6-18 years were examined. The first group (n=152) was represented by children with metabolically unhealthy obesity (MUO). The second group (n=100) consolidated of children with metabolically healthy obesity (MHO). Whole genome sequencing (CeGat, Germany) was performed in 52 children. Results. An association with the development of obesity was noted for T alleles rs61754624 (t=3.33) and rs10305457 (t=2.06); with MUO - for C alleles rs1042044 (t=2.23), rs1126476 (t=2.63), rs2235868 (t=2.82); T alleles rs61754624 (t=3.33), rs10305457 (t=2.06) GLP1R, p
