The Assessment and Sustainable Management of Sickle Cell Disease in the Indigenous Tharu Population of Nepal.

abstract：:We describe two novel α2 gene mutations that result in an altered amino acid sequence. In case 1, the α2 stop codon was mutated from TAA > TTA (HBA2: c.428A > T), resulting in an α2 protein chain extension of 31 amino acids. The new hemoglobin (Hb) variant was named Hb Kinshasa for the place of origin of the patient. ...
