We found that homozygous deletion of Gtf2i causes lethality during embryonic development with neural tube closure defects and exencephaly, consistent with other reports.
Among responsive mutants, folic acid supplementation reduces exencephaly and/or spina bifida aperta frequency in the Sp(2H), Sp, Cd, Cited2, Cart1, and Gcn5 mutants.Prevention ranges from 35 to 85%.

Knockout of Bbs7 combined with a hypomorphic Ift88 allele (orpk as a model for Shh dysfuction) results in embryonic lethality with e12.5 embryos having exencephaly, pericardial edema, cleft palate and abnormal limb development, phenotypes not observed in Bbs7(-/-) mice.
Grainyhead-like genes represent candidates for involvement in NTDs based on the presence of SB and exencephaly in mice carrying loss-of-function alleles of Grhl2 or Grhl3.
We identified a novel mouse mutant (<i>cleft lip/palate, edema and exencephaly; Clpex)</i> with a hypo-morphic mutation in <i>Post-Glycophosphatidylinositol Attachment to Proteins-2 (Pgap2)</i>, a component of the GPI biosynthesis pathway.

Mice homozygous for Hectd1-mutant showed early embryonic lethality with abnormal placental development and defective of neural tube closure resulting in exencephaly.
