    ### Response:
    Is Chiari malformation type 2 inherited? Chiari malformation type 2 typically occurs sporadically (in individuals with no history of the condition in the family). However, the exact cause of Chiari malformation type 2 is not known. Genes may play a role in predisposing an individual to the condition, but environmental factors (such as lack of proper vitamins or nutrients in the maternal diet during pregnancy) may also contribute to the condition.
