Erythrocytosis, familial, 5(ECYT5)

MedGen UID:
1638941
•Concept ID:
C4693552
•
Disease or Syndrome
Synonyms: ECYT5; ERYTHROCYTOSIS, FAMILIAL, 5
 
Gene (location): EPO (7q22.1)
 
Monarch Initiative: MONDO:0033483
OMIM®: 617907

Definition

Erythrocytosis-5 (ECYT5) is an autosomal dominant disorder characterized by increased red cell mass and typically elevated hemoglobin concentration and hematocrit. Some patients have increased serum EPO levels (summary by Zmajkovic et al., 2018). For a general phenotypic description and a discussion of genetic heterogeneity of familial erythrocytosis, see ECYT1 (133100). [from OMIM]

Clinical features

From HPO
Polycythemia
MedGen UID:
18552
•Concept ID:
C0032461
•
Disease or Syndrome
Polycythemia is diagnosed if the red blood cell count, the hemoglobin level, and the red blood cell volume all exceed the upper limits of normal.
See: Feature record | Search on this feature
Increased hematocrit
MedGen UID:
68692
•Concept ID:
C0239935
•
Finding
An elevation above the normal ratio of the volume of red blood cells to the total volume of blood.

Increased circulating hemoglobin concentration
MedGen UID:
108199
•Concept ID:
C0549448
•
Finding
Concentration of hemoglobin in the blood circulation above the upper limit of normal.
See: Feature record | Search on this feature
Elevated circulating erythropoietin concentration
MedGen UID:
1784401
•Concept ID:
C5539741
•
Finding
Increased concentration of erythropoietin in the blood circulation. Erythropoietin is a glycoprotein hormone produced by the peritubular cells of the kidney that stimulates red blood cell production.
