Names and Sequences
Functionality: | Globin gene causative mutation | Pathogenicity: | Pathogenic / Likely Pathogenic |
---|---|---|---|
Common Name: | CD 7/8 (+G) | HGVS Name: | HBB:c.24dupG |
Hb Name: | N/A | Protein Info: | β 8(+G); modified C-terminal sequence: (8)Glu-Val-Cys-Arg-Tyr-Cys-Pro-Val-Gly-Gln-Gly-Glu-Arg-Gly-(22)COOH |
Context nucleotide sequence:
GGTGCATCTGACTCCTGAGGAG [-/G] AAGTCTGCCGTTACTGCCCTGT (Strand: -)
Also known as:
Comments: The mutation causes a shift of the open globin reading frame, which leads to the development of a terminal codon in codon 22. The thalassaemic allele is associated with the mediterranean haplotype IX. The mutation presents with beta0-thalassaemia minor and slightly elevated HbF.
We follow the HGVS sequence variant nomenclature and IUPAC standards.

Note:
The impact thresholds provided in this section are based on the analyses performed in Tamana et.al. For any given tool, the impact thresholds defined for the set of variants with the same effect on function as the variant examined, are preferred over those defined for the full dataset.
