Also known as:
Comments: Found in a non-anaemic adult male originating from Lebanon with normal haematological parameters. In Hb Enschede, a substitution of one uncharged polar amino acid by another results in normal expression (24.0%).
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.
