Genes affected

SLC13A2 (HGNC:10917): (solute carrier family 13 member 2) The protein encoded by this gene is a sodium-coupled citrate transporter that is regulated by the chaperone activity of cyclophilin b. The encoded protein may play a role in the formation of kidney stones. [provided by RefSeq, Oct 2016]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1030C>T (p.R344W) alteration is located in exon 7 (coding exon 7) of the SLC13A2 gene. This alteration results from a C to T substitution at nucleotide position 1030, causing the arginine (R) at amino acid position 344 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
