ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV000757646 SCV000885946 likely benign not provided 2017-09-10 criteria provided, single submitter clinical testing The PKD1 c.6979C>T, p.Arg2327Trp variant (rs184394342) has been reported in an individual with autosomal dominant polycystic kidney disease (Rossetti 2012), but also found to occur with a PKD1 truncating variant (Mayo ADPKD variant database). It is observed in the general population databases at a frequency of 0.14 percent in the 1000 Genomes Project (7/5008 alleles), and 0.03 percent in the Genome Aggregation Database (55/175170 alleles). The arginine at residue 2327 is weakly conserved, but computational algorithms (Align GVGD: C0; Mutation Taster: polymorphism; PolyPhen-2: probably damaging; SIFT: damaging) are inconclusive on the variant's impact on the protein. Due to its co-occurrence with a truncating PKD1 variant, the p.Arg2327Trp variant is considered likely benign. References: Mayo ADPKD variant database: Rossetti S et al.
