Genes affected

SLCO1A2 (HGNC:10956): (solute carrier organic anion transporter family member 1A2) This gene encodes a sodium-independent transporter which mediates cellular uptake of organic ions in the liver. Its substrates include bile acids, bromosulphophthalein, and some steroidal compounds. The protein is a member of the SLC21A family of solute carriers. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Dec 2008]

The c.406G>A (p.G136R) alteration is located in exon 4 (coding exon 4) of the SLCO1A2 gene. This alteration results from a G to A substitution at nucleotide position 406, causing the glycine (G) at amino acid position 136 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
