Loss-of-function de novo mutations play an important role in severe human neural tube defects

Abstract excerpt

BACKGROUND: Neural tube defects (NTDs) are very common and severe birth defects that are caused by failure of neural tube closure and that have a complex aetiology. Anencephaly and spina bifida are severe NTDs that affect reproductive fitness and suggest a role for de novo mutations (DNMs) in their aetiology. METHODS: We used whole-exome sequencing in 43 sporadic cases affected with myelomeningocele or...
