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.
