RCV000503171 | SCV000592804 | uncertain significance | Polycystic kidney disease | no assertion criteria provided | clinical testing | The PKD1 p.Gly2459Cys variant was not identified in the literature nor was it identified in dbSNP, NHLBI GO Exome Sequencing Project, the Exome Aggregation Consortium database, Clinvitae, ClinVar, GeneInsight COGR, PKD1-LOVD and PKD1-LOVD 3.0 databases. The variant was identified in the ADPKD Mutation Database and classified as likely pathogenic. The p.Gly2459 residue is conserved across mammals and other organisms, and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the Cysteine variant may impact the protein; however, this information is not predictive enough to assume pathogenicity. The variant occurs outside of the splicing consensus sequence and 1 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing; however, this is not very predictive of pathogenicity. 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. |
