IthaID: 152

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Pathogenic / Likely Pathogenic
Common Name: CD 45 (-T) HGVS Name: HBB:c.138delT
Hb Name: N/A Protein Info: N/A

Context nucleotide sequence:

Also known as:

Comments: Found in two members of a Pakistani family presenting with heterozygous beta-thal trait. Found in two unrelated Pakistani individuals having children with transfusion-dependent thalassaemia. The loss of nt T in codon 45 results in a frameshift with a stop codon at codon 60 (TGA) terminating translation.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
