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 Likely_benign. Variant got -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.05010575).

BS2

High AC in GnomAd4 at 17 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Variant summary: PKD1 c.11957C>T (p.Ala3986Val) results in a non-conservative amino acid change located in the Polycystin cation channel, PKD1/PKD2 domain (IPR013122) of the encoded protein sequence. Three of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00017 in 182202 control chromosomes (gnomAD). This frequency is not higher than estimated for a pathogenic variant in PKD1 causing Polycystic Kidney Disease 1 (0.00017 vs 0.00049), allowing no conclusion about variant significance. c.11957C>T has been reported in the literature in an individual affected with Polycystic Kidney Disease 1, co-occurring with a pathogenic variant (PKD1 c.7863+1G>T) (Mallawaarachchi_2016). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One ClinVar submitter (evaluation after 2014) cites the variant as likely benign and two ClinVar submitters (evaluation after 2014) cite it as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

The PKD1 c.11957C>T variant is predicted to result in the amino acid substitution p.Ala3986Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.033% of alleles in individuals of European (Finnish) descent in gnomAD. At this position in several species is a valine (Val) including chicken, mouse, and rat. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
