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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 07, 2024The c.5974C>G (p.L1992V) alteration is located in exon 35 (coding exon 35) of the PKD1L2 gene. This alteration results from a C to G substitution at nucleotide position 5974, causing the leucine (L) at amino acid position 1992 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
