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]

Ambry Genetics

Feb 17, 2022

The c.3446T>G (p.L1149R) alteration is located in exon 21 (coding exon 21) of the PKD1L3 gene. This alteration results from a T to G substitution at nucleotide position 3446, causing the leucine (L) at amino acid position 1149 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
