IthaID: 3320

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: CD 16 GGC>GAC [Gly>Asp] HGVS Name: HBG1:c.50G>A
Hb Name: Hb F-Chori-I Protein Info: Aγ 16(A13) Gly>Asp

Protein sequence:

Also known as:

Comments: The variant was discovered in a blood cord sample for stem cell transplantation. Hb F-Chori-I is the counterpart of Hb J-Baltimore (beta-globin variant with normal functions unless associated with sickle cell or b-thal mutation). It seems that this new variant wouldn't lead to functionnal abnormalities.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
