Study Notes
Thalassemia
- A group of inherited blood disorders characterized by reduced or absent production of hemoglobin.
- Caused by mutations in genes responsible for hemoglobin synthesis.
- Hemoglobin is a protein in red blood cells that carries oxygen throughout the body.
Alpha Thalassemia
- Results from a genetic defect leading to impaired production of the alpha globin chain.
- Severity of the condition depends on the number of affected alpha genes.
Complications
- Thalassemia major: Most severe form, characterized by severe anemia, requiring frequent blood transfusions.
- Iron overload: Chronic blood transfusions lead to iron accumulation in the body.
Diagnosis
- Prenatal screening: Done during pregnancy to detect thalassemia in the fetus.
- Blood tests: Used to measure hemoglobin levels and red blood cell count.
Population Prevalence
- Mediterranean populations: Most commonly affected.
