Genes affected

SLC15A1 (HGNC:10920): (solute carrier family 15 member 1) This gene encodes an intestinal hydrogen peptide cotransporter that is a member of the solute carrier family 15. The encoded protein is localized to the brush border membrane of the intestinal epithelium and mediates the uptake of di- and tripeptides from the lumen into the enterocytes. This protein plays an important role in the uptake and digestion of dietary proteins. This protein also facilitates the absorption of numerous peptidomimetic drugs. [provided by RefSeq, Apr 2010]

The c.1741A>G (p.M581V) alteration is located in exon 21 (coding exon 21) of the SLC15A1 gene. This alteration results from a A to G substitution at nucleotide position 1741, causing the methionine (M) at amino acid position 581 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
