Genes affected

SLCO4C1 (HGNC:23612): (solute carrier organic anion transporter family member 4C1) SLCO4C1 belongs to the organic anion transporter (OATP) family. OATPs are involved in the membrane transport of bile acids, conjugated steroids, thyroid hormone, eicosanoids, peptides, and numerous drugs in many tissues (Mikkaichi et al., 2004 [PubMed 14993604]).[supplied by OMIM, Mar 2008]

The c.1724C>T (p.A575V) alteration is located in exon 10 (coding exon 10) of the SLCO4C1 gene. This alteration results from a C to T substitution at nucleotide position 1724, causing the alanine (A) at amino acid position 575 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
