SLC36A2 encodes proton-coupled amino acid transporter 2 (PAT2), a high-affinity cotransporter of glycine and proline coupled with the uptake of a proton in kidney and muscles (Schweikhard & Ziegler 2012). Defects in SLC36A2 can cause iminoglycinuria (IG; MIM:242600), an autosomal recessive abnormality of renal transport of glycine and the imino acids proline and hydroxyproline. Defects can also cause hyperglycinuria (HG; MIM:138500), a related disorder to IG which is characterised by excess glycine in the urine (Broer et al. 2008). Polymorphisms in the modifiers SLC6A18, 19 and 20, contribute to these phenotypes.
