Pediatr Hematol Oncol. 2019 Aug;36(5):302-308. doi: 10.1080/08880018.2019.1639863. Epub 2019 Aug 19.

Abstract

The human phosphoglycerate kinase-1 enzyme is the first of two energy generating steps in the glycolysis. Since its discovery in 1968, many pathologically mutated forms of PGK1 have been described. PGK1 is expressed in all tissues. The clinical manifestations of PGK1 deficiency are some combination of anemia, central nervous system and/or musculoskeletal manifestations. We describe a case of PGK1 in an African-American child, which to our knowledge, has never been described to date. The manifestations of PGK1-Detroit (c.1105A > C (p.Thr369Pro)) include hematologic and central nervous manifestations.

Keywords: Red blood cells; anemia; metabolism.
