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.497C>T (p.S166L) alteration is located in exon 5 (coding exon 5) of the SLCO2B1 gene. This alteration results from a C to T substitution at nucleotide position 497, causing the serine (S) at amino acid position 166 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
