Özet: Objective: Genetic and environmental risk factors constitute the major part of the etiology of autism, a multifactorial disorder. In this study, we aimed to investigate the MTHFR (Methyltetrahydrofolate Reductase Gene) C677T polymorphism in autistic children who were subjected to glutamate - caseinous and GAPS (Bowel and Psychology Syndrome) diets and to determine whether autism was related to decrease of enzyme activity caused by 677T allele of MTHFR gene. Materials and Methods: Thirty autistic and 90 healthy children were included in the study. DNA was obtained using a special commercial kit (GeneAll, Korea). Genotyping was performed by PCR - RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism) protocol and images were obtained by agarose gel electrophoresis. Results and Discussion: No statistically significant difference was found in the MTHFR 677T allele frequency as 13.33% in the patient group and 19.4% in the control group as p = 0.285. Due to the fact that the number of patients included in the study was not desired and not homogeneous, we recommend looking at MTHFR A1298C polymorphism and COMT (catechol-O-methyltransferase), BDNF (brain-derived neurotrophic factor), PTEN (phosphate and tensin homolog) genes.
