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.
