Also known as:
Comments: SNP associated with δ-thalassaemia. SNP was found in sickle cell anaemia patients with the Saudi-Indian (SI) or Arab-Indian (AI) haplotype and high HbF levels. There is no evidence that this SNP regulates HBG expression.
We follow the HGVS sequence variant nomenclature and IUPAC standards.
