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 GeneticsNov 18, 2022The c.1181G>A (p.R394H) alteration is located in exon 5 (coding exon 4) of the PIGR gene. This alteration results from a G to A substitution at nucleotide position 1181, causing the arginine (R) at amino acid position 394 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
