Comments: Found in a 20-year-old Chinese male presented with microcytic hypochromatosis. The deletion was detected by MLPA analysis and removed the entire HBA2, HBA1, HBQ and HBZ gene, as well as the major regulatory element HS-40, resulting in the loss of more than 134 kb from the a-globin chain. The exact breakpoints were not determined, as MLPA failed to identify an upstream break location. Pedigree analysis revealed that the proband inherited the novel deletion from his father.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
