Genes affected

PKDREJ (HGNC:9015): (polycystin family receptor for egg jelly) This intronless gene encodes a member of the polycystin protein family. The encoded protein contains 11 transmembrane domains, a receptor for egg jelly (REJ) domain, a G-protein-coupled receptor proteolytic site (GPS) domain, and a polycystin-1, lipoxygenase, alpha-toxin (PLAT) domain. This protein may play a role in human reproduction. Alternative splice variants have been described but their biological natures have not been determined. [provided by RefSeq, Jul 2008]

Ambry Genetics

Nov 06, 2023

The c.6608T>C (p.M2203T) alteration is located in exon 1 (coding exon 1) of the PKDREJ gene. This alteration results from a T to C substitution at nucleotide position 6608, causing the methionine (M) at amino acid position 2203 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
