Genes affected

PIGR (HGNC:8968): (polymeric immunoglobulin receptor) This gene is a member of the immunoglobulin superfamily. The encoded poly-Ig receptor binds polymeric immunoglobulin molecules at the basolateral surface of epithelial cells; the complex is then transported across the cell to be secreted at the apical surface. A significant association was found between immunoglobulin A nephropathy and several SNPs in this gene.[provided by RefSeq, Sep 2009]

Ambry Genetics

Feb 21, 2024

The c.1079A>C (p.K360T) alteration is located in exon 5 (coding exon 4) of the PIGR gene. This alteration results from a A to C substitution at nucleotide position 1079, causing the lysine (K) at amino acid position 360 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
