Genes affected

PKD1L1 (HGNC:18053): (polycystin 1 like 1, transient receptor potential channel interacting) This gene encodes a member of the polycystin protein family containing 11 transmembrane domains, a receptor for egg jelly (REJ) domain, and a polycystin-1, lipoxygenase, alpha-toxin (PLAT) domain. The encoded protein may play a role in the male reproductive system. Alternative splice variants have been described but their biological nature has not been determined.

The c.8189G>A (p.G2730E) alteration is located in exon 54 (coding exon 54) of the PKD1L1 gene. This alteration results from a G to A substitution at nucleotide position 8189, causing the glycine (G) at amino acid position 2730 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
