---|---|---|---|
Common Name: | CD 2/3 (+T); CD 5 (-C) | HGVS Name: | HBB:c.[9dupT; 17delC] |
Hb Name: | Hb Antalya | Protein Info: | β 2 - 5 His-Leu-Thr-Pro replaced with His-Ser-Asp-Ser |
Context nucleotide sequence:
AACAGACACCATGGTGCAT[-/T]CTGACTC [-/C] TGAGGAGAAGTCTGCCGTTACTGC (Strand: -)
Also known as:
Comments: Found in a proband with beta-thalassaemia trait. The amino acid residues Leu-Thr-Pro (codons 3-5) of the normal allele in the β-globin gene are changed to Ser-Asp-Ser, respectively, by insertion of a nt T between codon 2 and codon 3 (CAT [+T] CTG) and deletion of a nt C at codon 5 (CCT>C-T).
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.
