Also known as:

Comments: The novel α0-thal deletion found in combination with the rightward –α3.7 deletion, causing Hb H disease in a 3-month-old female from India. The deletion removed HBA2 and HBA1 and spanned the region from HBZ to HBQ1, with the upstream major regulatory element HS-40 remaining intact. The 5’ breakpoint is localised between the positions 143655 and 149367 while the 3’ breakpoint is localized between 181204 and 206338 (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.
