IthaID: 2479

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: Toledo HGVS Name: NG_000007.3:g.11835_13826del
Hb Name: N/A Protein Info: β nts range (-58711 - -56718)

Also known as: 1992 bp deletion

Comments: The deletion exclusively affects only the HS3 element of the βLCR. Found in a male presented with very mild microcytosis, indicating that HS3 deletion does not severely impair the β-gene expression.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
