IthaID: 3315

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: CD 56 GGC>GAC [Gly>Asp] HGVS Name: HBD:c.170G>A
Hb Name: Hb A2-Shah Alam Protein Info: N/A

Protein sequence:

Also known as:

Comments: HBD:c.170G>A substitutes glycine with aspartic (missense). The index was identified with heterozygous β+ IVS 1-5 (G>C) inherited from the father. His HbA2 and HbF was 2.5% and 3.0%, respectively. The HBD was inherited from the mother. His mother’s HbA2 was 1.4%. CE showed additional fraction at Zone 6 (mother 1.0%, child 1.2%). Possible HBA and HBB variants were ruled out by sequencing.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
