With the help of multiple genetic tools, we performed comprehensive genetic analysis of HPFH and (δβ)(0) -thalassaemia in Indian population and could define the molecular basis of these conditions in this population. We also identified two novel HPFH mutations, 49.98 kb (HPFH-9) and 86.7 kb (HPFH-10) deletions, in this population.
