Genes affected

SLC6A18 (HGNC:26441): (solute carrier family 6 member 18) The SLC6 family of proteins, which includes SLC6A18, act as specific transporters for neurotransmitters, amino acids, and osmolytes like betaine, taurine, and creatine. SLC6 proteins are sodium cotransporters that derive the energy for solute transport from the electrochemical gradient for sodium ions (Hoglund et al., 2005 [PubMed 16125675]).[supplied by OMIM, Apr 2010]

Ambry Genetics

Jul 11, 2022

The c.55C>T (p.P19S) alteration is located in exon 1 (coding exon 1) of the SLC6A18 gene. This alteration results from a C to T substitution at nucleotide position 55, causing the proline (P) at amino acid position 19 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
