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 -6 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.9).
BP6
Variant 16-2089719-A-C is Benign according to our data. Variant chr16-2089719-A-C is described in ClinVar as [Likely_benign]. Clinvar id is 3054230.Status of the report is no_assertion_criteria_provided, 0 stars.
BS2
High AC in GnomAd4 at 25 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
