Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | N/A |
|---|---|---|---|
| Common Name: | CD 104 (-A) | HGVS Name: | HBB:c.313delA |
| Hb Name: | N/A | Protein Info: | N/A |
Context nucleotide sequence:
TGCACGTGGATCCTGAGAACTTC [A/-] GGGTGAGTCTATGGGACGCTTGA (Strand: -)
Also known as:
Comments: Found in a 12-year-old Chinese boy in compound heterozygosity with HBB:c.126_129delCTTT [IthaID:147] and the -α4.2 [IthaID:301]. Patient presented with severe β-thalassemia and required regular blood transfusions. The A deletion caused a frameshift at codon 104, which resulted in an elongated protein of 156 amino acid residues.
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.
