Comments: The alpha 118 residue has a key role for the interaction of the alpha globin chain with the chaperone protein AHSP. This interaction prevents the alpha chain from premature degradation. In Hb Cervantes, its hyper-unstability is due to a decreased affinity for AHSP.
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.
