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 (TERC), telomere loss results in the failure of neural tube closure, primarily at the forebrain and midbrain.
