    ### Instruction:
    Is nonsyndromic holoprosencephaly inherited ?
    ### Response:
    Nonsyndromic holoprosencephaly is inherited in an autosomal dominant pattern, which means an alteration in one copy of a gene in each cell is usually sufficient to cause the disorder. However, not all people with a gene mutation will develop signs and symptoms of the condition.
