IthaID: 3663



Names and Sequences

Functionality: Globin gene causative mutation
Common Name: HS-40 deletion HGVS Name: NC_000016.10:g.(47217_113592)_(113687_143639)del
Hb Name: N/A Protein Info: N/A

Also known as:

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.
