SLC6A18 (Solute Carrier Family 6 Member 18) is a Protein Coding gene. Diseases associated with SLC6A18 include Hartnup Disorder and Hyperglycinuria. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and NRF2 pathway. 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.
