Genes affected

SLC15A2 (HGNC:10921): (solute carrier family 15 member 2) The mammalian kidney expresses a proton-coupled peptide transporter that is responsible for the absorption of small peptides, as well as beta-lactam antibiotics and other peptide-like drugs, from the tubular filtrate. This transporter, SLC15A2, belongs to the same gene family as SLC15A1 (MIM 600544), the proton-coupled peptide transporter found in the small intestine (Liu et al, 1995 [PubMed 7756356]).[supplied by OMIM, Feb 2011]

The c.959G>A (p.G320D) alteration is located in exon 11 (coding exon 11) of the SLC15A2 gene. This alteration results from a G to A substitution at nucleotide position 959, causing the glycine (G) at amino acid position 320 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
