Hemoglobin Variants: Biochemical Properties and Clinical

 · Hemoglobin variants and thalassemias are two genetically distinct hemoglobin abnormalities, Thalassemias are characterized by a reduced synthesis of the normal globin chain due to gene deletions or mutations, The most common thalassemias are alpha- and beta-thalassemias, The hemoglobin variants are caused by amino acid substitutions in either globin chain, Globally, more than 1800 hemoglobin variants …

Hemoglobin Variants – an overview

Hemoglobin variants

Diseases affecting hemoglobin synthesis and function are extremely common worldwide More than 1000 naturally occurring human hemoglobin variants with single amino acid substitutions throughout the molecule have been discovered mainly through their clinical and/or laboratory manifestations These variants alter hemoglobin structure and biochem-

Les campagnes de dépistage néo-natal concernent aussi les variants d’hémoglobine, elles ont permis de dépister beaucoup d’enfants porteurs, Ceci est dû aux nouvelles technologies utilisées, et non pas à une augmentation de la prévalence des mutations, La santé de ces enfants n’est pas affectée par le fait d’avoir une seule copie du gène muté; mais ces dépistages ont grandement augmenté le besoin d’information concernant les variants …

Les variants d’hémoglobine sont des formes anormales d’hémoglobine, Les molécules d’hémoglobines Hb ou Hbg sont composées de quatre sous-unités de globine chaîne protéique formée d’acides aminés liées chacune à un groupe hème partie qui contient le fer, L’hémoglobine, présente dans tous les globules rouges, transporte l’oxygène depuis les poumons jusqu’aux cellules des tissus de l’organisme,

The most common Hb variants worldwide are HbS HbE HbC and HbD All of these Hb variants have single amino acid substitutions in the Hb beta chain HbF is the major hemoglobin during intrauterine life; by the end of the first year HbF falls to values close to adult levels of approximately 1%, However, elevated HbF levels can occur in certain pathologic conditions or with hereditary persistence of fetal hemoglobin, In a series of …

 · Some of the most common hemoglobin variants include hemoglobin S, the primary hemoglobin in people with sickle cell disease that causes the red blood cell to become misshapen sickle, decreasing the cell’s survival; hemoglobin C, which can cause a minor amount of hemolytic anemia; and hemoglobin E, which may cause no symptoms or generally mild symptoms,

More than 1000 naturally occurring human hemoglobin variants with single amino acid substitutions throughout the molecule have been discovered mainly through their clinical and/or laboratory manifestations These variants alter hemoglobin structure and biochemical properties with physiological effects ranging from insignificant to severe Studies of these mutations in patients and in the laboratory have produced a wealth of information on hemoglobin …
