Study Notes
Thalassemia Syndromes
- Erythrocyte indices generally indicate Microcytic Anemia in Thalassemia syndromes.
Characteristics of Thalassemia
- Thalassemia is characterized by reduced synthesis of globin chains of hemoglobin, leading to anemia.
Inheritance Pattern
- Thalassemia has an Autosomal Recessive inheritance pattern.
Alpha Thalassemia
- The result of total lack of α-globin production is Hydrops Fetalis, which is usually fatal.
- Gene deletions on Chromosome 16 can cause Alpha Thalassemia.
Beta Thalassemia
- The result of total lack of β-globin production is Beta Thalassemia Major, which is a severe anemia.
- Point mutations on Chromosome 11 can cause Beta Thalassemia.
Miscellaneous
- The Greek word for Great Sea is "Thalassa", which is where the name Thalassemia comes from.
- Thalassemia is the most common single gene disorder.
