SUCCESSFUL REHABILITATION OF PATIENT DISABLED BY THE AUTISTIC SPECTRUM DISORDER AND THE MODIFIED EPIGENETIC STATUS (POLYMORPHISMS DRD2 2137 T/T, MTRR 66 A/G, MTHFR 677 C/T, MTHFR 1298 A/C) - CASE REPORT.

Autism spectrum disorders (ASD) are considered an epidemic - only in the last 5 years the incidence of pathology has increased from 1: 166 to 1:68 children. The main role in the pathogenesis of ASD currently belongs to the violation of the epigenetic status in the form of gene polymorphisms. An example is the polymorphic variants of the genes of the folate-methionine cycle enzymes, which regulate the epigenetic status through a methylation process. The article presents a case of autism spectrum disorder against the background of impaired epigenetic status (metabolic dopamine neurotransmitters and the methylation cycle). Individually selected metabolic correction based on biochemical parameters allowed improving behavior, stimulating speech development, stopping long subfebrile and hypersalivation.
