IthaID: 474

Names and Sequences

Functionality: Globin gene causative mutation
Common Name: CD 19 (GCC>GAC) [Ala>Asp] HGVS Name: HBA2:p.Ala20Asp | HBA1:p.Ala20Asp
Hb Name: Hb J-Kurosh Protein Info: α2 or α1 19(AB1) Ala>Asp

Protein sequence:

Also known as:

Comments: Codon 19 is presumed to be GCG but may be GCC in some populations; a one base change of GCC can result in GAC and explain the Ala->Asp replacement
