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.399G>A (p.M133I) alteration is located in exon 1 (coding exon 1) of the SLC22A14 gene. This alteration results from a G to A substitution at nucleotide position 399, causing the methionine (M) at amino acid position 133 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
