IthaID: 3546

Names and Sequences

Functionality: Globin gene causative mutation
Common Name: CD 130 TAT>-AT HGVS Name: HBD:c.391delT
Hb Name: Hb A2-Gaslini 1 Protein Info: p.Tyr131Ilefs?

Context nucleotide sequence:

Also known as:

Comments: Single nucleotide deletion (-T) generating a frameshift with elongation of the δ-globin chain to 212 amino acids. Found in a heterozygous state. Presents with normochromic normocytic red cell morphology, HbA2 level 1.6% and HbF level 0.6%. No visible peak on HPLC, hence presumed to be unstable.
