Genes affected

PKD1L2 (HGNC:21715): (polycystin 1 like 2 (gene/pseudogene)) This gene encodes a member of the polycystin protein family. This protein may function as a G-protein-coupled component or regulator of cation channel pores. The long isoform of this protein contains 11 transmembrane domains, a latrophilin/CL-1-like GPCR proteolytic site (GPS) domain, and a polycystin-1, lipoxygenase, alpha-toxin (PLAT) domain. Alternative splicing results in multiple transcript variants encoding distinct isoforms. This gene is a polymorphic pseudogene in humans. [provided by RefSeq, May 2022]

The c.5594A>G (p.E1865G) alteration is located in exon 32 (coding exon 32) of the PKD1L2 gene. This alteration results from a A to G substitution at nucleotide position 5594, causing the glutamic acid (E) at amino acid position 1865 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
