IthaID: 3559

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Variant of Uncertain Significance
Common Name: CD 65 AAG>GAG [Lys>Glu] HGVS Name: HBB:c.196A>G
Hb Name: Hb Guangxi Protein Info: β 65(E9) Lys>Glu

Protein sequence:

Also known as:

Comments: Found in a female from Guilin municipality in the Guangxi Zhuang Autonomous Region. Variant interfered with Hb A1c analysis by CapillaryS2 resulting in no Hb A1c value. It was characterized by both CE and HPLC (VARIANT II). The isopropanol test for Hb stability was negative and no inclusions were observed under the microscope.
