Genes affected

SLC22A15 (HGNC:20301): (solute carrier family 22 member 15) Organic ion transporters, such as SLC22A15, transport various medically and physiologically important compounds, including pharmaceuticals, toxins, hormones, neurotransmitters, and cellular metabolites. These transporters are also referred to as amphiphilic solute facilitators (ASFs).[supplied by OMIM, Apr 2004]

The c.473T>A (p.F158Y) alteration is located in exon 4 (coding exon 4) of the SLC22A15 gene. This alteration results from a T to A substitution at nucleotide position 473, causing the phenylalanine (F) at amino acid position 158 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
