IthaID: 3297

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Pathogenic / Likely Pathogenic
Common Name: CD 11-13 (-9bp): (-GTTACTGCC) HGVS Name: HBB:c.34_42delGTTACTGCC
Hb Name: Hb JC-Paz Protein Info: N/A

Context nucleotide sequence:

Also known as:

Comments: Found as a heterozygote. The deletion results in loss of an alanine, a valine and a threonine of the 'A' α-helix of the β-globin chain. Reported in the literature as HBB:c.29_37delCTGCCGTTA, which does not follow the HGVS Sequence Variant Nomeclature recommendations.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
