Detection of Alpha Globin mutations
Prenatal detection of Alpha Thalassemia.
Thalassemias are group of autosomal recessive disorder of hemoglobin synthesis characterized by the reduction in the rate of synthesis of globin chain of one or more globin chain. The decreased synthesis of globin chain may result from gene deletion, non-sense mutation or mutation that affects the transcription or stability of mRNA products. In the alpha-thalassemias, there is absence or decreased production of beta-globin subunits, whereas in the beta- thalassemias, there is absent or reduced production of beta globin subunits.
