Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: CD 5 CCT>ACT [Pro>Thr] HGVS Name: HBD:c.16C>A
Hb Name: Hb A2-Partinico Protein Info: δ 5(A2)Pro>Thr

Context nucleotide sequence:

Protein sequence:

Also known as:

Comments: Found in cis to the allele β+ thal IVS-I-110 G>A in five members of a Sicilian family. Detected by HPLC; overlaps HbA2 peak which is partially split. The residue 5(A2) of the δ-globin chain is in the alpha helix region; no functional alteration was predicted.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
