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]
