ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV001285473 SCV001471904 uncertain significance Polycystic kidney disease, adult type 2020-03-20 criteria provided, single submitter clinical testing The PKD1 c.9313C>T; p.Arg3105Trp variant (rs1376608198) is reported in the literature in the compound heterozygous state with the PKD1 p.Arg2765Cys variant in an individual affected with polycystic kidney disease, although siblings with only one of the variants had a single cyst, suggesting these variants may be hypomorphic (Rossetti 2009). The p.Arg3105Trp variant is found in the general population with an overall allele frequency of 0.0022% (5/226230 alleles, including a single homozygote) in the Genome Aggregation Database. The arginine at codon 3105 is highly conserved, and computational analyses (SIFT: damaging, PolyPhen-2: benign) predict conflicting effects of this variant on protein structure/function. Due to limited information, the clinical significance of the p.Arg3105Trp variant is uncertain at this time. References: Rossetti S et al. Incompletely penetrant PKD1 alleles suggest a role for gene dosage in cyst initiation in polycystic kidney disease. Kidney Int. 2009 Apr;75(8):848-55.
