Hb Name: N/A Protein Info: N/A

Also known as:

Comments: The deletion spans about 225 kb on the α-globin gene cluster (positions 46407-271806 according to the UCSC Genome Browser, March 2006). The 5' breakpoint is located within the POLR3K gene, upstream of the distal regulatory elements, and the 3' breakpoint is located within a region between the RGS11 and AXIN1 genes.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
