Genes affected

SLC22A14 (HGNC:8495): (solute carrier family 22 member 14) This gene encodes a member of the organic-cation transporter family. It is located in a gene cluster with another member of the family, organic cation transporter like 3. The encoded protein is a transmembrane protein which is thought to transport small molecules and since this protein is conserved among several species, it is suggested to have a fundamental role in mammalian systems. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

The c.677T>C (p.F226S) alteration is located in exon 3 (coding exon 3) of the SLC22A14 gene. This alteration results from a T to C substitution at nucleotide position 677, causing the phenylalanine (F) at amino acid position 226 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
