▶Evaluation of 64 candidate single nucleotide polymorphisms as risk factors for neural tube defects in a large Irish study populationAssociationN=2,079Tonia C. Carter et al.(2011)· American Journal of Medical Genetics Part A
This case-control and family-based study evaluated 64 SNPs in 34 genes for associations with spina bifida in 558 Irish case-families and 994 controls. Spina bifida was significantly associated with LEPR rs1805134 (GRR: 1.5, P = 0.0264) and COMT rs737865 (GRR: 1.4, P = 0.0206), with additional confirmations of previous findings in MTHFR 677C>T and other genes, suggesting roles for leptin signaling and methylation pathways in neural tube defect pathogenesis.
▶Folate pathway and nonsyndromic cleft lip and palateAssociationN=445Susan H. Blanton et al.(2011)· Birth Defects Research Part A: Clinical and Molecular Teratology
This family-based association study examined 14 folate pathway genes using 89 SNPs in 445 NSCLP families (317 non-Hispanic White, 128 Hispanic) to identify genetic variants contributing to nonsyndromic cleft lip and palate. Evidence for association was found with SNPs in NOS3 and TYMS in the non-Hispanic White group (rs2373929/NOS3, rs502396/TYMS, and others), and with MTR, BHMT2, MTHFS, and SLC19A1 in the Hispanic group (rs1422086/BHMT2, rs2115540/MTHFS significant after Bonferroni correction). Multiple gene-gene interactions were detected, with CBS and MTHFD1 showing the most extensive interactions. Significant interactions were also found between several SNPs and maternal smoking and one SNP (rs651646/FOLR2) with offspring sex.
About BHMT2
Homocysteine is a sulfur-containing amino acid that plays a crucial role in methylation reactions. Transfer of the methyl group from betaine to homocysteine creates methionine, which donates the methyl group to methylate DNA, proteins, lipids, and other intracellular metabolites. The protein encoded by this gene is one of two methyl transferases that can catalyze the transfer of the methyl group from betaine to homocysteine. Anomalies in homocysteine metabolism have been implicated in disorders ranging from vascular disease to neural tube birth defects such as spina bifida. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2010]
