Also known as:
Comments: SNP associated with risk of stroke in the Cooperative Study of Sickle Cell Disease (CSSCD) (92 cases; 1306 controls). The association was replicated in an independent sample of pediatric sickle cell disease patients acquired from the Stroke With Transfusion Changing to Hydrxyurea (SWiTCH) trial (130 cases; 103 controls enrolled from the HUSTLE study), in which the T allele associated with increased stroke risk. SNP (allele A) associated with an increased risk of high-risk transcranial Doppler in a pediatric Brazilian cohort with SCA (n=338).
We follow the HGVS sequence variant nomenclature and IUPAC standards.
