RCV000507997 | SCV000604791 | likely pathogenic | not provided | 2018-04-17 | criteria provided, single submitter | clinical testing | The PKD1 c.3496G>A, p.Gly1166Ser variant (rs573566419) has been reported in a patient diagnosed with autosomal dominant polycystic kidney disease (Phakdeekitcharoen 2000), and is considered likely pathogenic by the Mayo ADPKD variant database. It is observed at a low frequency of 0.004% (8/177768 alleles) in the Genome Aggregation Database, but is considered a low confidence variant in the database. The glycine at residue 1166 is highly conserved, but computational algorithms (PolyPhen-2: possibly damaging; SIFT: tolerated) are inconclusive on the variant's impact on the protein. Functional characterization of the variant in archaea ortholog of the PKD domain shows reduced thermodynamic and mechanical stability (Ma 2009), consistent with protein structure analyses predicting a disruption of the PKD domain (Ma 2009, Phakdeekitcharoen 2000). Based on the above information, the variant is classified as likely pathogenic. References: Mayo ADPKD variant database: http://pkdb.mayo.edu Ma L et al.
