Alpha Gene Sequencing

Description: 
Molecular analysis of the alpha globin gene allows for the confirmation and identification of mutations that give rise to haemoglobin variants and thalassaemias. Alpha gene sequencing detects and identifies mutations, delections and insertions within the alpha 1 and alpha 2 genes that can be associated with quantitative or qualitative variations in the haemoglobin molecule and their associated hereditary diseases.
Clinical details: 
Alpha gene mutation screening for thalassaemias and Hb variants
