Genes affected

SLC22A12 (HGNC:17989): (solute carrier family 22 member 12) The protein encoded by this gene is a member of the organic anion transporter (OAT) family, and it acts as a urate transporter to regulate urate levels in blood. This protein is an integral membrane protein primarily found in epithelial cells of the proximal tubule of the kidney. An elevated level of serum urate, hyperuricemia, is associated with increased incidences of gout, and mutations in this gene cause renal hypouricemia type 1. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2013]

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 217 of the SLC22A12 protein (p.Thr217Met). This variant is present in population databases (rs121907893, gnomAD 0.05%). This missense change has been observed in individual(s) with clinical features of hypouricemia (PMID: 12024214, 14694169, 23043931, 31591475). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 3513). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects SLC22A12 function (PMID: 12024214). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
