Department of Pathology and Laboratory Medicine, Sinai Health System RCV001354292 SCV001548871 uncertain significance not provided no assertion criteria provided clinical testing The PKD1 p.Met1092Thr variant was not identified in the literature nor was it identified in the following databases: dbSNP, ClinVar, GeneInsight-COGR, LOVD 3.0, ADPKD Mutation Database, or the PKD1-LOVD. The variant was not identified in the control databases: the 1000 Genomes Project, the NHLBI GO Exome Sequencing Project, the Exome Aggregation Consortium (August 8th 2016), or the Genome Aggregation Database (Feb 27, 2017). The p.Met1092 residue is not conserved in mammals but one out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the c.3275_3276delinsCC variant may impact the protein; however, this information is not predictive enough to assume pathogenicity. This variant is an in-frame deletion-insertion resulting in the replacement of a methionine residue for a threonine residue at codon 1092; the impact of this alteration on PKD1 protein function is not known. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
