IthaID: 3603

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: -α6.9 HGVS Name: NG_000006.1:g.29785_36746del
Hb Name: N/A Protein Info: N/A

Also known as:

Comments: The deletion spans approximately 6.9 kb on the alpha-globin gene cluster, removing the α2 gene but leaving the α1 gene intact. The 5' deletion breakpoint lies in the HBAP1 gene. Deletion breakpoints were determined by MLPA and Gap-PCR analyses. Reported in a compound heterozygous state with --SEA deletion in a proband presenting with HbH disease.
