IthaID: 2465


Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Pathogenic / Likely Pathogenic
Common Name: CD 19 GCG>GC- HGVS Name: HBA2:c.60delG
Hb Name: N/A Protein Info: p.His21Thrfs*29

Context nucleotide sequence:
GGCCGCCTGGGGTAAGGTCGGCGC [-/G] CACGCTGGCGAGTATGGTGCGGAG (Strand: +)

Also known as:

Comments: Detected as a homozygote and heterozygote in Iranian subjects with elevated Hb Bart's levels. The deletion of nt 'G' in codon 19 (GCG) creates a frameshift leading to a premature stop codon at codon 48 (TGA).

We follow the HGVS sequence variant nomenclature and IUPAC standards.
