    ### Instruction:
    Is megalencephalic leukoencephalopathy with subcortical cysts inherited ?
    ### Response:
    All cases of megalencephalic leukoencephalopathy with subcortical cysts caused by mutations in the MLC1 gene (type 1) and some cases caused by mutations in the HEPACAM gene (type 2A) are inherited in an autosomal recessive pattern. Autosomal recessive inheritance means both copies of a gene in each cell have mutations.
