IthaID: 3392

Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: Variant of Uncertain Significance
Common Name: CD 80 AAC>AGC [Asn>Ser] HGVS Name: HBB:c.242A>G
Hb Name: Hb Moncloa Protein Info: β80(EF4)Asn>Ser

Context nucleotide sequence:

Protein sequence:

Also known as:

Comments: Found as a heterozygote during routine health check. Perceived to be haematologically silent. Its chromatographic profile suggests a probable interference during the monitoring of glycated haemoglobin (HbA1c).
