IthaID: 2954
Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | Pathogenic / Likely Pathogenic |
|---|---|---|---|
| Common Name: | CD 42 TTT>TT- | HGVS Name: | HBB:c.129delT |
| Hb Name: | Hb Yala | Protein Info: | β 42 (-T); modified C-terminal sequence: (42)Leu-Ser-Pro-Leu-Gly-Ile-Cys-Pro-Leu-Leu- Met-Leu-Leu-Trp-Ala-Thr-Leu-Arg-(60)COOH |
Also known as:
Comments: Found as a heterozygote with the Hb E variant. The deletion causes a frameshift at codon 42 which results in a premature termination codon (PTC) at codon 60.
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.
