IthaID: 3318

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: CD 116 CGC>CTC [Arg>Leu] HGVS Name: HBD:c.350G>T
Hb Name: Hb A2-Lepore Protein Info: δ 116(G18) Arg>Leu

Protein sequence:

Also known as: Hb A2-India

Comments: This new delta-globin variant was linked in cis with a beta(0)-thalassaemia mutation (CD 15 TGG>TAG). It was originally confused with Hb Lepore since it migrates in the same CE-CLHP window.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
