Confirm Beta Thalassemia State with complete information on Mutations
Beta Thalassemia is a common inherited blood Disorder that reduces production of hemoglobin due to mutation in one or bothcopies of beta globin gene (HBB). HBB gene produces globin protein which is a part of Hemoglobin. The severity of anemia caused by Beta Thalassemia depends on which mutations are present.
Carrier screening of pregnant women (Prenatal Screening), preferably performed in first trimester.
• Any individual with a raised Red Blood cell Count or reduced MCV or reduced MCH
• Pre marital Thalassemia Carrier screening of couples.
• Thalassemia screening in consanguineous (blood relation/cousin) marriage.
• Carrier screening of individuals belonging to high-risk communities.
• Newborn screening for Sickle Cell Disease by Dried Blood Spot (DBS).
Hemoglobinopathy is a kind of genetic defect that results in abnormal structure of one of the globin chains of the hemoglobin molecule.
Hemoglobinopathies are inherited single-gene disorders; in most cases, they are inherited as autosomal co-dominant traits. Common hemoglobinopathies include sickle-cell disease.
