IthaID: 3393



Names and Sequences

Functionality: Globin gene causative mutation
Common Name: 3.5 kb deletion HGVS Name: NC_000011.10:g.5224302-5227791del3490bp
Hb Name: N/A Protein Info: N/A

Also known as: Thai, 3485 bp deletion

Comments: The deletion spans approximately 3.5 kb on the β-globin gene cluster, removing the β-globin gene promoter and the whole β-globin gene. The 5' and 3' breakpoints are located at positions 5224302 and 5227791, respectively (GRCh37/hg19). Co-inheritance with a β+ mutation led to a severe transfusion-dependent anemia.
