WebG6PD is remarkable for its genetic diversity. Many variants of G6PD, mostly produced from missense mutations, have been described with wide ranging levels of enzyme activity and associated clinical symptoms.

WebJul 12, 2012 · A reduced RBC S/V ratio has long been recognized to contribute to pathogenesis of several RBC disorders, 9-11 including hereditary spherocytosis (HS), the most common cause of inherited chronic hemolytic anemia in Northern Europe and North America, with an estimated incidence of 1 in 2000. 11 The clinical presentation of HS can …
WebHereditary spherocytosis is an inherited a disorder of the red cell membrane (cytoskeleton protein deficiency) which results in red blood cells that are fragile causing premature breakdown of red blood cells and anemia (hemolytic anemia) 3). The red blood cells have a normal shape at first – flat discs, like a doughnut without the hole. WebSpherocytosis is the presence of spherocytes in the blood, i.e. erythrocytes ( red blood cells) that are sphere-shaped rather than bi-concave disk shaped as normal. Spherocytes are found in all hemolytic anemias to some …
WebSummary G6PD deficiency is the most common genetic cause of chronic and drug-, food-, or infection-induced hemolytic anemia. G6PD catalyzes the first reaction in the pentose phosphate pathway, which is the only NADPH-generation process in mature red cells; therefore, defense against oxidative damage is dependent on G6PD. WebHereditary elliptocytosis, also known as ovalocytosis, is an inherited blood disorder in which an abnormally large number of the person's red blood cells are elliptical rather than the typical biconcave disc shape. Such morphologically distinctive erythrocytes are sometimes referred to as elliptocytes or ovalocytes. It is one of many red-cell membrane defects.
