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.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.9).
BP6
Variant 16-2114368-G-A is Benign according to our data. Variant chr16-2114368-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 256934.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr16-2114368-G-A is described in Lovd as [Likely_benign].
BP7
Synonymous conserved (PhyloP=-1.72 with no splicing effect.
BS1
Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000696 (106/152274) while in subpopulation EAS AF = 0.00657 (34/5172). AF 95% confidence interval is 0.00483. There are 1 homozygotes in GnomAd4. There are 52 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position FAILED quality control check.
BS2
High AC in GnomAd4 at 106 AD gene.
