[[http://www.uniprot.org/uniprot/EPOR_HUMAN EPOR_HUMAN]] Defects in EPOR are the cause of familial erythrocytosis type 1 (ECYT1) [MIM:[http://omim.org/entry/133100 133100]]. ECYT1 is an autosomal dominant disorder characterized by increased serum red blood cell mass, elevated hemoglobin and hematocrit, hypersensitivity of erythroid progenitors to erythropoietin, erythropoietin low serum levels, and no increase in platelets nor leukocytes. It has a relatively benign course and does not progress to leukemia.<ref>PMID:8506290</ref> <ref>PMID:8174675</ref> <ref>PMID:8608241</ref> [[http://www.uniprot.org/uniprot/EPO_HUMAN EPO_HUMAN]] Genetic variation in EPO is associated with susceptbility to microvascular complications of diabetes type 2 (MVCD2) [MIM:[http://omim.org/entry/612623 612623]]. These are pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis.

[[http://www.uniprot.org/uniprot/EPOR_HUMAN EPOR_HUMAN]] Receptor for erythropoietin. Mediates erythropoietin-induced erythroblast proliferation and differentiation. Upon EPO stimulation, EPOR dimerizes triggering the JAK2/STAT5 signaling cascade. In some cell types, can also activate STAT1 and STAT3. May also activate the LYN tyrosine kinase.  Isoform EPOR-T acts as a dominant-negative receptor of EPOR-mediated signaling. [[http://www.uniprot.org/uniprot/EPO_HUMAN EPO_HUMAN]] Erythropoietin is the principal hormone involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass.
