    ### Instruction:
    Is multiple cutaneous and mucosal venous malformations inherited ?
    ### Response:
    VMCM is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to increase the risk of developing venous malformations.  Some gene mutations are acquired during a person's lifetime and are present only in certain cells.
