    ### Instruction:
    Is Erythropoietic protoporphyria inherited ?
    ### Response:
    How is erythropoietic protoporphyria (EPP) inherited? EPP is inherited in an autosomal recessive manner. In most cases, affected individuals have one severe (loss-of-function) mutation that is inherited from one parent, and another weak (low-expression) mutation that is inherited from the other parent.
