Comments: The novel α-thal deletion found in combination with the rightward –α3.7 deletion causing Hb H disease in a 44-year-old man. Patient presented with moderate microcytic hypochromic anemia and electrophoresis analysis showed slightly low Hb A2, with a typical Hb H band (5.3%). The deletion removed the major regulatory element of the α-globin locus, HS-40. The 5’ breakpoint is localised between the positions 47217 and 113592 while the 3’ breakpoint is localized between 113687 and 143639 (coordinates: GRCh38.p13, NC_000016.10). As the breakpoints are not clearly defined the deletion size is just an approximation.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
