IthaID: 3532



Names and Sequences

Functionality: Disease modifying mutation Pathogenicity: N/A
Common Name: rs56291099 HGVS Name: NC_000010.11:g.70171322G>A

Context nucleotide sequence:
TTTATTGTGCACTTATGTTCCA [G>A] GCAGAGCACTGGGTACTTTGC (Strand: +)

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.
