Genetic association of the glycine cleavage system genes and myelomeningocele.

ABSTRACT:

Background

Neural tube defects (NTDs) are one of the most common congenital birth defects, with myelomeningocele (MM) being the most severe form compatible with life. Recent studies show a link between mitochondrial folate one carbon metabolism and NTDs by means of the glycine cleavage system (GCS). We hypothesize that single nucleotide polymorphisms and novel variants in the coding regions of the GCS genes increase the risk for MM.

Methods

DNA was obtained from 96 subjects with MM born before the United States mandated folic acid fortification of grains in 1998. Primers were designed for polymerase chain reaction amplification and sequencing of all exons in the AMT gene, one of four genes in the GCS, followed by identification of single nucleotide polymorphisms and novel va
