SLC6A18 encodes a neutral amino acid transporter B(0)AT3 which has preference for the amino acid glycine. It is abundantly expressed in the kidney, specifically the S2/3 segments of the kidney proximal tubule (Broer & Gether 2012, Schweikhard & Ziegler 2012). Iminoglycinuria (IG; MIM:242600) or hyperglycinuria (HG; MIM:138500) can arise from defects in SLC36A2, encoding a proton-coupled amino acid transporter 2 (PAT2), a high-affinity cotransporter of glycine and proline. Mutation in SLC6A18 may contribute to both IG and HG (Broer et al. 2008).
