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]

The c.6397G>A (p.V2133I) alteration is located in exon 1 (coding exon 1) of the PKDREJ gene. This alteration results from a G to A substitution at nucleotide position 6397, causing the valine (V) at amino acid position 2133 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
