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 -7 ACMG points.

PM1

In a hotspot region, there are 8 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 2 benign, 9 uncertain in NM_001009944.3

BP4

Computational evidence support a benign effect (MetaRNN=0.04360816).

BP6

Variant 16-2103752-G-A is Benign according to our data. Variant chr16-2103752-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 440092.

BS1

Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000857 (125/1458146) while in subpopulation AMR AF = 0.00251 (112/44702). AF 95% confidence interval is 0.00213. There are 0 homozygotes in GnomAdExome4. There are 50 alleles in the male GnomAdExome4 subpopulation. Median coverage is 34. This position passed quality control check.
