Also known as:
Comments: Insertion of eight amino acids (Ser-Ala-Gln-Val-Lys-Gly-His-Gly) due to a 24 bp duplication from nucleotide 157 to 180. The His(E7) residue appears to be in its normal position, while the eight additional residues are probably inserted at the beginning of helix E, increasing its size, but with mild effects on folding and heme contact.
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.
