Invitae | RCV002647713 | SCV003523525 | uncertain significance | Autosomal recessive polycystic kidney disease | 2022-10-20 | criteria provided, single submitter | clinical testing | This sequence change affects codon 3770 of the PKHD1 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the PKHD1 protein. This variant also falls at the last nucleotide of exon 62, which is part of the consensus splice site for this exon. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individual(s) with polycystic kidney disease (Invitae). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
