    Is Anencephaly inherited ?
    ### Response:
    Is anencephaly inherited? Most cases of anencephaly are sporadic, which means they occur in people with no family history of anencephaly or other neural tube defects (NTDs). In some cases, it may be associated with a chromosome abnormality, a severe malformation syndrome, or disruption of the amniotic membrane.
