IthaID: 3404



Names and Sequences

Functionality: Globin gene causative mutation
Common Name: CD 133-135 (-AGCACCG) HGVS Name: HBA2:c.400_406delAGCACCG
Hb Name: Hb Aalesund Protein Info: α2 133-135 (-AGCACCG); modified C-terminal sequence

Comments: Found as a heterozygote. The 7 base-pair deletion creates a frameshift in codon 133 and the new reading frame ends in a termination codon two positions downstream, in the last exon of the HBA2 gene. The frameshift variant will most likely bypass the nonsense-mediated decay mechanism and a unstable truncated protein will be translated. Interfers with HbA1c measurement, causing a falsely high HbA1c with certain instruments.
