RESUMEN
The study covered genetically determined lipid metabolism disorders due to oral intake of technogenic hyperchlorination drinkable water products. Findings are that overweight and obese children in a main group appeared to have serum chloroform level 2.3 times higher than that in a reference group. In oral intake of hyperchlorination drinkable water products, the study revealed main genes having polymorphism associated with endocrine disorders: overweight and obesity--APOE, PPARG, HTR2A, characterizing antioxidant system state--SOD2 and detoxication--SULTA. Polymorphism of candidate genes HTR2A and SOD2 was characterized by increased occurrence of mutant homo-- and heterozygous genotype, relative risk of pathologic allele presence in population exceeded the refrence group values. Probability of increased serum serotonin and lower Cu/Zn in children with mutant homozygous genotype HTR2A and SOD2 is 1.2-1.3 times higher than in those with heterozygous and normal homozygous genotypes.

Evaluation of effects caused by environmental peroral exposure to chlorine organic compounds revealed that individuals with AG variation of HTR2A gene are a community with increased sensitivity to chloroform and a risk group for lipid and carbohydrates metabolism disorders. Individual risk of endocrine disorders (ICD: E67.8 excessive nutrition and E66.0 obesity) in these individuals is higher than in general population exposed to chloroform at residence (HQ1.72). Serum serotonin level, that is functionally connected with HTR2A gene, is 1.3 times lower vs. the reference group value.
