Genes affected
PKD1L3 (HGNC:21716): (polycystin 1 like 3, transient receptor potential channel interacting) This gene encodes a member of the polycystin protein family. The encoded protein contains 11 transmembrane domains, a latrophilin/CL-1-like GPCR proteolytic site (GPS) domain, and a polycystin-1, lipoxygenase, alpha-toxin (PLAT) domain. This protein may function as a component of cation channel pores.[provided by RefSeq, Apr 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.3373G>A (p.E1125K) alteration is located in exon 20 (coding exon 20) of the PKD1L3 gene. This alteration results from a G to A substitution at nucleotide position 3373, causing the glutamic acid (E) at amino acid position 1125 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
