IthaID: 189
Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | Pathogenic / Likely Pathogenic |
|---|---|---|---|
| Common Name: | CD 88 (+T) | HGVS Name: | HBB:c.266dupT |
| Hb Name: | N/A | Protein Info: | β 88(+T); modified C-terminal sequence: (88)Leu-(89)Glu-COOH |
Context nucleotide sequence:
ACCTCAAGGGCACCTTTGCCACACT [-/T] GAGTGAGCTGCACTGTGACAAGCTG (Strand: -)
Also known as:
Comments: Found in a heterozygous state in one person of Asian Indian origin. The insertion of a nt T in codon 88 creates a shift in the reading frame with a premature stop codon at codon 90 (TGA).
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.
