HK deficiency, Non-spherocytic hemolytic anemia due to hexokinase deficiency, NSHA due to HK1 deficiency, and Hexokinase deficiency hemolytic anemia.[1]
Hexokinase deficiency is an autosomal recessive disorder.
Hexokinase deficiency is an extremely rare
autosomal recessive condition that falls under the category of erythroenzymopathies, or defects in
red cell enzymes.[2] Hexokinase deficiency manifests is associated with chronic nonspherocytic
hemolytic anemia.[3]Hemolytic anemia seems to be the only clinical sign of hexokinase deficiency.[4] In 1967 the first case of hexokinase deficiency was described by Valentine et al,[5] since then, less than 50 cases have been reported.[6]
Signs and symptoms
The main clinical feature of affected individuals is mild to severe
hemolytic anemia that lasts a lifetime. However, there have also been rare reports of multiple malformations, including
psychomotor retardation.[7] Intrauterine fetal death results from a total loss of HK1 expression.[8]
Hemolytic anemias' systemic symptoms, which include
weakness,
pallor, exhaustion, and
dizziness, are similar to those of other
anemias. There may be splenic
icterus, jaundice, and/or splenomegaly.[9]
Extremely impacted people may develop neonatal
hyperbilirubinemia and subsequently need transfusions on a regular basis to treat their uncontrollable anemia. Anemia is absent and
hemolysis is completely compensated for, for those with mild disease. Nonetheless, these patients typically have
reticulocytosis,
splenomegaly, and
jaundice.
Gallstones can be seen as early as childhood.[6]
