Symptoms of anemia include feeling tired and having pale skin. [1] Other symptoms of thalassemia include bone problems, an enlarged spleen, yellowish skin, pulmonary hypertension, and dark urine. [1] Slow growth may occur in children. [1] Symptoms and presentations of thalassemia can change over time.
Beta-thalassemia; Other names: Microcytemia, beta type [1] Beta thalassemia genetics, the picture shows one example of how beta thalassemia is inherited. The beta globin gene is located on chromosome 11. A child inherits two beta globin genes (one from each parent). Specialty: Hematology: Types: Thalassemia minor, intermediate and major [2] Causes
Alpha-thalassemia mental retardation syndrome (ATRX), also called alpha-thalassemia X-linked intellectual disability syndrome, nondeletion type or ATR-X syndrome, [1] is an X-linked recessive condition associated with a mutation in the ATRX gene. [2] Males with this condition tend to be moderately intellectually disabled and have physical ...
Alpha-thalassemia (α-thalassemia, α-thalassaemia) is a form of thalassemia involving the genes HBA1 [5] and HBA2. [6] Thalassemias are a group of inherited blood conditions which result in the impaired production of hemoglobin , the molecule that carries oxygen in the blood. [ 7 ]
Sickle cell-beta thalassemia. Sickle cell beta thalassemia. Other names. Sickle cell-β thalassemia. Specialty. Hematology. Sickle cell-beta thalassemia is an inherited blood disorder. The disease may range in severity from being relatively benign and like sickle cell trait to being similar to sickle cell disease. [1][2]
Sickle cell trait describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous). Those who are heterozygous for the sickle cell allele produce both normal and ...
Though only definitively diagnosable by genetic sequence testing, including a G band analysis, ATR-16 syndrome may be diagnosed from its constellation of symptoms. It must be distinguished from ATR-X syndrome, a very similar disease caused by a mutation on the X chromosome, and cases of alpha-thalassemia that co-occur with intellectual disabilities with no underlying genetic relationship.
Hemoglobin E disease (EE) First thirty amino acid of normal Hb (on top) and of HbE (down). Hemoglobin E disease results when the offspring inherits the gene for HbE from both parents. At birth, babies homozygous for the hemoglobin E allele do not present symptoms because they still have HbF (fetal hemoglobin). In the first months of life, fetal ...
