Description:
Molecular diagnosis of alpha thalassaemia. Deletions in the HBA1 and HBA2 genes are found in over 98% of alpha thalassemia cases with seven founder mutations accounting for ~95% of all alpha thalassemia cases: -α3.7, -α4.2, -(α)20.5, --SEA, --MED, --FIL, and - THAI. Patients with non-deletional forms of alpha thalassemia often present with more severe disease. The most common point variant found in Asian populations is Hemoglobin Constant Spring (HbCS) which abolishes the canonical termination codon in the HBA2 gene, c.427T>C (p.*143Gln)
