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 was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.88).
BP6
Variant 16-2097245-G-C is Benign according to our data. Variant chr16-2097245-G-C is described in ClinVar as Likely_benign. ClinVar VariationId is 3780134.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000653 (94/1439582) while in subpopulation SAS AF = 0.000997 (83/83242). AF 95% confidence interval is 0.000824. There are 1 homozygotes in GnomAdExome4. There are 75 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
