Genes affected
SLCO2B1 (HGNC:10962): (solute carrier organic anion transporter family member 2B1) This locus encodes a member of the organic anion-transporting polypeptide family of membrane proteins. The protein encoded by this locus may function in regulation of placental uptake of sulfated steroids. Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2010]

The c.749G>A (p.R250H) alteration is located in exon 6 (coding exon 6) of the SLCO2B1 gene. This alteration results from a G to A substitution at nucleotide position 749, causing the arginine (R) at amino acid position 250 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
