Comments: Protein change: G335R. Compound heterozygote with p.R331W. Abnormally low levels of the red cell enzyme pyruvate kinase, a known cause of CNSHA. Severe, transfusion dependent hemolytic anemia. Persistent expression of fetal hemoglobin and expression of large quantities of embryonic globins in post-natal life.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
