IthaID: 171
Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | Pathogenic / Likely Pathogenic |
|---|---|---|---|
| Common Name: | CD 62-64 (-7bp) | HGVS Name: | HBB:c.189_195delTCATGGC |
| Hb Name: | N/A | Protein Info: | N/A |
Context nucleotide sequence:
GGGCAACCCTAAGGTGAAGGC [TCATGGC/-] AAGAAAGTGCTCGGTGCCTTT (Strand: -)
Also known as:
Comments: The 7bp deletion caused a shift in the normal reading frame of the β-globin coding sequence and created a stop codon at codon 87. This led to an altered β chain with only 23 residues and to a β0 thalassaemia phenotype.
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.
