IthaID: 75



Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Pathogenic / Likely Pathogenic
Common Name: CD 16 GGC>GG- HGVS Name: HBB:c.51delC
Hb Name: N/A Protein Info: β 16 (-C); modified C-terminal sequence: (16)Gly-(17)Arg-COOH

Context nucleotide sequence:
AGTCTGCCGTTACTGCCCTGTGGGG [C/-] AAGGTGAACGTGGATGAAGTTGGTG (Strand: -)

Also known as:

Comments: One additional case reported the G deletion in combination with the CD 10 (GCC>GCA) [IthaID: 65] in a male presented with severe anaemia (Hb 6.9 g/dl) and decreased level of MCV (71.8 fL), MCH (24 pg) and RBC (2.94 X 10^12/L). Hb analysis showed increased Hb A2 (6.3 %) and Hb F (19.7 %) levels.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
