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 Benign. Variant got -11 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.5).

BP6

Variant 16-2103759-G-C is Benign according to our data. Variant chr16-2103759-G-C is described in Lovd as [Likely_benign].

BP7

Synonymous conserved (PhyloP=0.73 with no splicing effect.

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000922 (14/151804) while in subpopulation EAS AF= 0.00278 (14/5028). AF 95% confidence interval is 0.00168. There are 0 homozygotes in gnomad4. There are 7 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.

BS2

High AC in GnomAd4 at 14 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
