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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 05, 2023The c.1168G>T (p.A390S) alteration is located in exon 5 (coding exon 4) of the PIGR gene. This alteration results from a G to T substitution at nucleotide position 1168, causing the alanine (A) at amino acid position 390 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
