Genes affected

PKHD1 (HGNC:9016): (PKHD1 ciliary IPT domain containing fibrocystin/polyductin) The protein encoded by this gene is predicted to have a single transmembrane (TM)-spanning domain and multiple copies of an immunoglobulin-like plexin-transcription-factor domain. Alternative splicing results in two transcript variants encoding different isoforms. Other alternatively spliced transcripts have been described, but the full length sequences have not been determined. Several of these transcripts are predicted to encode truncated products which lack the TM and may be secreted. Mutations in this gene cause autosomal recessive polycystic kidney disease, also known as polycystic kidney and hepatic disease-1. [provided by RefSeq, Jul 2008]

Variant summary: PKHD1 c.12106C>T (p.Arg4036Trp) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 7.6e-05 in 250920 control chromosomes (gnomAD). This frequency is not significantly higher than expected for a pathogenic variant in PKHD1 causing Polycystic Kidney and Hepatic Disease (7.6e-05 vs 0.0071), allowing no conclusion about variant significance. However, the variant was also reported in Japanese healthy control databases (HGVD-Kyoto and jMorp) with a frequency of 0.006 (including 1 homozygote in HGVD-Kyoto database). This frequency is somewhat close to the estimated maximal expected allele frequency for a pathogenic PKHD1 variant, therefore this variant might represent a benign polymorphism found primarily in populations of East Asian origin (HGVD). To our knowledge, no occurrence of c.12106C>T in individuals affected with Polycystic Kidney and Hepatic Disease and no experimental evidence demonstrating its impact on protein function have been reported. Two other ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
