IthaID: 185


Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Pathogenic / Likely Pathogenic
Common Name: CD 82/83 (-G) HGVS Name: HBB:c.251delG
Hb Name: N/A Protein Info: N/A

Context nucleotide sequence:
CCTGGCTCACCTGGACAACCTCAAGG [-/G] CACCTTTGCCACACTGAGTGAGCT (Strand: -)

Also known as:

Comments: Found in an Azerbaijanian patient with β0-thalassaemia [PMID: 2525253]. Found in three different alleles of unrelated patients with β-thalassaemia major from Azerbaijan [PMID: 1483699]. Found in seven members of two families of Czech decent [PMID: 1740317]. Found in a Yugoslavian family of Croatian nationality with a heterozygosity for β-thalassaemia [PMID: 1517107]. The deletion of a nt G in codons 82/83 changes the reading frame with a stop codon at codon 88 resulting in a premature termination of translation.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
