Names and Sequences

Functionality: Disease modifying mutation Pathogenicity: N/A
Common Name: CD 56 GTG > GGG HGVS Name: NT_010393.16:g.31479870T>G

Context nucleotide sequence:
ACATGGTGACTGTGGTGGAGGACTGGATGAACTTCTACATCAACTATTACAGGCAGCAGG [T/G] GACAGGGGAGCCCCAAGAGCGAGACAAGGCTCTGCAGGAGCTTCGGCAAG (Strand: +)

Also known as: V56G, rs186590045

Comments: The AHSP structural variant produced by the G allele shows decreased interaction with alpha globin and is thus predicted as an aggravating modifier of the thalassemias, in particular of beta-thalassaemia. This assumption is supported by the observation of moderate thalassaemia in a homozygote for AHSP(V56G) during his first year of life.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
