    ### Instruction:
    Is familial erythrocytosis inherited ?
    ### Response:
    Familial erythrocytosis can have different inheritance patterns depending on the gene involved.  When the condition is caused by mutations in the EPOR, EGLN1, or EPAS1 gene, it has an autosomal dominant pattern of inheritance. Autosomal dominant inheritance means one copy of the altered gene in each cell is sufficient to cause the disorder.
