  • Description: <jats:title>Abstract</jats:title><jats:sec><jats:title>BACKGROUND</jats:title><jats:p>Neural tube defects (NTDs) are the second most common birth defects, after congenital heart defects. Telomerase, the reverse transcriptase that maintains telomere DNA, has been shown to be important for neural tube development and bilateral symmetry in the brain. In knockout mice null for the telomerase RNA component (<jats:italic>TERC</jats:italic>), telomere loss results in the failure of neural tube closure, primarily at the forebrain and midbrain.</jats:p></jats:sec><jats:sec><jats:title>METHODS</jats:title><jats:p>We investigated <jats:italic>TERC</jats:italic> for variants that may predispose to human NTDs in 477 NTD cases with a variety of phenotypic presentations.</jats:p></jats:sec><jats:sec><jats:title>RESULTS</jats:title><jats:p>Two novel single nucleotide polymorphisms were identified in the human <jats:italic>TERC</jats:italic> sequence but showed no association with the NTD phenotype.</jats:p></jats:sec><jats:sec><jats:title>CONCLUSIONS</jats:title><jats:p>Variants in <jats:italic>TERC</jats:italic> are unlikely to be a major risk factor for the most common form of human NTDs, lumbosacral myelomeningocele.
