镰状细胞病(sickle cell disease)是指红细胞含有血红蛋白s(hbs)的一种常染色体显性遗传的溶血性疾病。本病有三种类型: ①hbs的纯合子称为镰状细胞性贫血; ②杂合子称为镰状细胞特征(sickle cell trait); ③hbs与地中海贫血或其他异常hb基因组合成的双重杂合子称为混合型镰状细胞综合征。

Sickle cell trait Definition Sickle cell trait or sickle trait is also known as hemoglobin genotype AS. Hemoglobin is the oxygen carrying protein in red blood cells. It carries oxygen from the lungs into the body and transports it to the organs, muscles, and tissues. Normal hemoglobin is calle...

Sickle Cell Disease (Clinical) Sickle cell disease (SCD) is a group of genetic disorders in which an abnormal Hb molecule (Hb S) transforms RBCs into sickle-shaped cells, resulting in chronic anemia, vasoocclusive episodes, pain, and organ damage. Sickle cell trait, which is the heterozygous...

Individuals may carry the sickle cell trait without producing any symptoms. Sickle cell disease occurs where HbS makes up more than 50% of the hemoglobin (Bolton-Maggs and Thomas, 2008). Hemoglobin S crystallizes causing the red blood cells to take on a “sickle” or “C” shape and ...
The production of HbS is influenced by the number of α-thalassemia genes present and the amount of HbS. By definition, among individuals with sickle cell trait, the HbS level is <50%. The life span of people with sickle cell trait is normal, and serious complications are extremely rare. ...
sickle cell trait n. A hereditary condition, usually harmless and without symptoms, in which an individual carries only one mutated hemoglobin gene for sickle cell anemia. The sickle cell trait confers resistance to some forms of fatal malaria. ...
