IthaID: 3325

Names and Sequences

Functionality: Globin gene causative mutation
Common Name: CD 144 AAG>AGG [Lys>Arg] HGVS Name: HBB:c.434A>G
Hb Name: Hb Heze Protein Info: β144(HC1)Lys>Arg

Context nucleotide sequence:

Protein sequence:

Comments: The mutation associates with a mild β-thal phenotype in the heterozygote state, but leads to a β-thal intermedia (β-TI) phenotype when interacting with β0-thal. The lysine at β144 is located at the HC1 position, in the central pocket near to the C-terminal of the β-globin chain.
