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]

The c.3398T>G (p.F1133C) 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 3398, causing the phenylalanine (F) at amino acid position 1133 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
