Here, we present results for a novel LeanSequencingTM process to identify a combination of 18 β-thalassemia mutations (including the sickle cell anemia mutation, HbS, and structural variants HbC and HbE) and 2 hemochromatosis mutations in a multi-ethnic population of 274 pediatric and adolescent patients treated at Afzaal Memorial Thalassemia Foundation in Karachi, Pakistan. This evidence concerns the gene KRT88P and hemochromatosis type 1.
