IthaID: 3339



Names and Sequences

Functionality: Disease modifying mutation Pathogenicity: N/A
Common Name: rs2146323 HGVS Name: NG_008732.1:g.12143C>A

Context nucleotide sequence:
GGACTTACGTTAGATTTTGGAAGGA [A/C] TTGCCTGATTCGGAAGCTCCAAAGA (Strand: +)

Also known as:

Comments: SNP (C>A) strongly associated with high HbF levels in β-thalassaemia patients and hence, a milder clinical phenotype of the disease. The A allele also associated with hydroxyurea treatment efficacy (high HbF levels) in SCD/β-thalassaemia patients.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
