We report the analysis of the 677C T mutation on the 5,10-methylenetetrahydrofolate reductase gene in Turkish controls and cases of neural tube defects. Mutation analysis of 91 patients with neural tube defects, 72 mothers, 63 fathers, and 93 healthy controls has been made by polymerase chain reaction and allele specific restriction digestion with Hinf I. We did not find a significant difference in the 677C T allele and genotype distribution among the patients with neural tube defects, their parents, and the control group. This result suggests that another mutation in the folate-related enzyme genes could be responsible for neural tube defects in Turkey. None of the mothers of patients with neural tube defects was advised to use folic acid as recommended to prevent neural tube defects. An immediate attempt to establish an education program for healthcare providers and women of childbearing age is crucial in Turkey. Furthermore, fortification of foods with folate would be a better approach. (J Child Neurol 1999;14:159-161).
