Genes affected
PKD1 (HGNC:9008): (polycystin 1, transient receptor potential channel interacting) This gene encodes a member of the polycystin protein family. The encoded glycoprotein contains a large N-terminal extracellular region, multiple transmembrane domains and a cytoplasmic C-tail. It is an integral membrane protein that functions as a regulator of calcium permeable cation channels and intracellular calcium homoeostasis. It is also involved in cell-cell/matrix interactions and may modulate G-protein-coupled signal-transduction pathways. It plays a role in renal tubular development, and mutations in this gene cause autosomal dominant polycystic kidney disease type 1 (ADPKD1). ADPKD1 is characterized by the growth of fluid-filled cysts that replace normal renal tissue and result in end-stage renal failure. Splice variants encoding different isoforms have been noted for this gene. Also, six pseudogenes, closely linked in a known duplicated region on chromosome 16p, have been described.

ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 12 ACMG points.
PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.022459727 fraction of the gene. Cryptic splice site detected, with MaxEntScore 3.3, offset of -35, new splice context is: gcagggccccgccccggcAGcgt. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 16-2091176-T-C is Pathogenic according to our data. Variant chr16-2091176-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 447955.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

PKD1-related disorder Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | Jun 21, 2023 | The PKD1 c.11713-2A>G variant is predicted to disrupt the AG splice acceptor site and interfere with normal splicing. This variant has been reported to segregate with polycystic kidney disease in an affected father and child (Audrézet et al 2016. PubMed ID: 26139440). This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating it is rare. Variants that disrupt the consensus splice acceptor site in PKD1 are expected to be pathogenic. This variant is interpreted as pathogenic. - |
