IthaID: 3214

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: 44.6 kb deletion HGVS Name: NC_000016.10:g.144215_188841del
Hb Name: N/A Protein Info: N/A

Also known as:

Comments: The deletion spans 44.6 kb on the α-globin gene cluster removing both of the duplicated α-globin genes, while the upstream regulatory element HS-40 is left intact. Breakpoints were localized to positions 193637-199336 at the 5' end, and positions 237170-256305 at the 3’ end (hg19) using MLPA. Deletion breakpoints were determined by array comparative genomic hybridization.
