GeneDx RCV001765970 SCV002000670 likely pathogenic not provided 2022-01-28 criteria provided, single submitter clinical testing Not observed at a significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV003226487 SCV003923286 uncertain significance not specified 2023-03-22 criteria provided, single submitter clinical testing Variant summary: PKHD1 c.8480T>C (p.Leu2827Pro) results in a non-conservative amino acid change located in the second G8 domain (IPR019316) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 249824 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.8480T>C in individuals affected with Polycystic Kidney And Hepatic Disease and no experimental evidence demonstrating its impact on protein function have been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. One laboratory classified the variant as likely pathogenic. Based on the evidence outlined above, the variant was classified as uncertain significance.
