    ### Instruction:
    Is Mitochondrial encephalomyopathy lactic acidosis and stroke-like episodes inherited ?
    ### Response:
    How is mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) inherited? MELAS is caused by mutations in mitochondrial DNA (mtDNA) and is therefore transmitted by maternal inheritance (also called mitochondrial inheritance). This type of inheritance applies to all conditions caused by genes in mtDNA.
