IthaID: 124


Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Pathogenic / Likely Pathogenic
Common Name: IVS I [3' end] (+22bp) HGVS Name: NG_000007.3:g.70807_70828dup
Hb Name: N/A Protein Info: N/A

Also known as:

Comments: The duplication found in heterozygosity with Hb E. The 22bp tandem duplication around the intron 1/exon 2 boundary, resulting in a premature stop codon. The deduced amino acid sequence yielded only 37-residue peptide.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
