Context nucleotide sequence:

Also known as:

Comments: SNP is located within 2KB 5' of SAR1A gene. SNP is associated with a higher percent of HbF with hydroxyurea (HU) treatment (69 cases,107 controls) and with a significant change in absolute HbF levels after 2 years of HU treatment (n=32) in African Americans with sickle cell disease (SCD) acquired from the Sickle Cell Pulmonary Hypertension Screening Study. SNP did not associate with baseline HbF or HU-induced HbF levels in SCD patients from Cameroon (n=484). Note: Published SNP position 'chr10:71601084 (hg18)' is remapped on the GRCh38.p13 genome assembly.
