IthaID: 3582



Names and Sequences

Functionality: Neutral polymorphism Pathogenicity: N/A
Common Name: IVS II-579 G>C HGVS Name: HBB:c.316-272G>C

TTTCCCTAATCTCTTTCTTTCA [G/C] GGCAATAATGATACAATGTATCA (Strand: -)

Also known as:

Comments: This mutation is an innocuous SNP associated with a well-characterised cryptic splice acceptor site in HBB. The cryptic splice acceptor is activated by mutation IthaID 214, leading to aberrant splicing, inclusion of a pseudo-exon in the HBB mRNA and beta-thalassaemia. Mutation IthaID 214 retains residual normal splicing activity, and in presence of the causative mutation this SNP may thus conceivably increase normal splicing and ameliorate the associated phenotype.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
