| Hb Name: | Hb Palencia | Protein Info: | N/A |
Also known as:
Comments: A β-like globin chain composed of an internal δ-globin fragment and β-globin N-terminal and C-terminal sequences. The βδβ hybrid gene comprises both the promoter region and the IVS-II of the HBB gene, and its synthesis is like that of β-globin. The δ sequence bears mutations that could confer it with anti-sickling properties. It is most likely the result of a cross-linking between a Lepore-type gene and an HBB gene. Detected during a routine health check in an otherwise asymptomatic individual.
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.
