Genes affected

SLC7A9 (HGNC:11067): (solute carrier family 7 member 9) This gene encodes a protein that belongs to a family of light subunits of amino acid transporters. This protein plays a role in the high-affinity and sodium-independent transport of cystine and neutral and dibasic amino acids, and appears to function in the reabsorption of cystine in the kidney tubule. Mutations in this gene cause non-type I cystinuria, a disease that leads to cystine stones in the urinary system due to impaired transport of cystine and dibasic amino acids. Alternate transcript variants, which encode the same protein, have been found for this gene. [provided by RefSeq, Jul 2011]

The c.1388A>G (p.Q463R) alteration is located in exon 12 (coding exon 11) of the SLC7A9 gene. This alteration results from a A to G substitution at nucleotide position 1388, causing the glutamine (Q) at amino acid position 463 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
