IthaID: 3224
Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | Pathogenic / Likely Pathogenic |
|---|---|---|---|
| Common Name: | -90 (C>G) | HGVS Name: | HBB:c.-140C>G |
| Hb Name: | N/A | Protein Info: | N/A |
Also known as:
Comments: The -90 C>G mutation is a change in the 90th nucleotide upstream the transcription initiation site. Its putative pathological effect is a decreased binding rate of KLF1, thereby reducing the expression of the HBB gene.
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.
