Comments: Identified in a 1-year-old boy presenting with reduced MCV and MCH levels and hypochromic microcytic anaemia. In silico pathogenicity prediction using MutationTaster suggested that this variant may affect protein function and alter splice sites; however, it was classified as a polymorphism by the same predictor.
