Red cell adenylate kinase (AK) deficiency is a rare hereditary erythroenzymopathy associated with moderate to severe nonspherocytic hemolytic anemia and, in some cases, with mental retardation and psychomotor impairment. To date, diagnosis of AK deficiency depends upon demonstration of low enzyme activity in red blood cells and detection of mutations in AK1 gene. To investigate the molecular bases of the AK deficiency, we characterized five variants of AK1 isoenzyme-bearing mutations (118G>A, 190G>A, 382C>T, 418-420del, and 491A>G) found in AK-deficient patients with chronic hemolytic anemia.

Abstract
Red cell adenylate kinase (AK) deficiency is a rare hereditary erythroenzymopathy associated with moderate to severe nonspherocytic hemolytic anemia and, in some cases, with mental retardation and psychomotor impairment. To date, diagnosis of AK deficiency depends upon demonstration of low enzyme activity in red blood cells and detection of mutations in AK1 gene. To investigate the molecular bases of the AK deficiency, we characterized five variants of AK1 isoenzyme-bearing mutations (118G>A, 190G>A, 382C>T, 418-420del, and 491A>G) found in AK-deficient patients with chronic hemolytic anemia.File in questo prodotto:
