Erythrocytosis due to a mutation in the erythropoietin receptor gene.
BRIT J HAEMATOL
407 - 410.
Familial erythrocytosis, associated with high haemoglobin levels and low serum erythropoietin (Epo), has been shown to co-segregate with a sequence repeat polymorphism at the 5' region of the erythropoietin receptor (EpoR) in a large Finnish family.We have investigated the cause of erythrocytosis in an English boy. Sequencing of the cytoplasmic region of the EpoR detected a de novo transition mutation of G to A at nucleotide 6002. This mutation resulted in the formation of a stop codon at amino acid 439 with the loss of 70 amino acids from the carboxy terminus. The mutation (G6002A) has arisen independently in a Finnish family and de novo in this English boy. Patients with unexplained erythrocytosis and low serum Epo levels should be investigated for EpoR mutations.
