RCV001292038 | SCV001480654 | likely benign | Polycystic kidney disease | no assertion criteria provided | clinical testing | The PKD1 c.-187G>A variant was not identified in the literature nor was it identified in the dbSNP, ClinVar, Genesight-COGR, ADPKD Mutation Database, PKD1-LOVD (unavailable) databases. The variant was identified in control databases in 1 of 27242 chromosomes at a frequency of 0.00004 in the European Non-Finnish population and not other populations, increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The c.-187G>A variant is not expected to have clinical significance because it is not located in a known consensus splice site.In addition, 1 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing; 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 although we would lean towards a more benign role for this variant. This variant is classified as likely benign. |
