IthaID: 3294

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: 22 kb deletion HGVS Name: N/A
Hb Name: N/A Protein Info: N/A

Also known as:

Comments: The deletion spans approximately 22 kb on the α-globin gene cluster (positions 159487-181215 according to the UCSC Genome Browser, March 2006), removing both α-globin genes. The 5' breakpoint is located within a region usptream of the HBZP pseudogene, and the 3' breakpoint is located within a region between the HBQ1 and LUC7L genes. It is similar to a deletion reported in [PMID: 1715793].
