    ### Instruction:
    Is African iron overload inherited ?
    ### Response:
    African iron overload seems to run in families, and high iron in a family's diet seems to be the major contributor to development of the condition. There also may be a genetic contribution, but the inheritance pattern is unknown. People with a specific variation in the SLC40A1 gene may inherit an increased risk of this condition, but not the condition itself.
