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.

Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

The PKD1 p.Asp3782Asp variant was identified as polymorphism in 6 of 550 proband chromosomes (frequency: 0.01) from individuals or families with ADPKD (Rossetti 2012, Rossetti 2002). The variant was also identified in the following databases: in dbSNP (ID: rs145955373) as “With Benign allele”, ClinVar (1x, as benign by Prevention Genetics), ADPKD Mutation Database (as likely neutral). The variant was not identified in LOVD 3.0, or PKD1-LOVD databases. The variant was identified in control databases in 1274 of 276110 (5 homozygous) chromosomes at a frequency of 0.004614 in the following populations: African in 30 of 23896 chromosomes (freq. 0.0012), other in 40 of 6440 chromosomes (freq. 0.006), Latino in 106 of 34408 chromosomes (freq. 0.003), European in 669 of 125862 (2 homozygous) chromosomes (freq. 0.005), Ashkenazi Jewish in 36 of 10114 chromosomes (freq. 0.0035), East Asian in 1 of 18836 chromosomes (freq. 0.00005), Finnish in 118 of 25778 chromosomes (freq. 0.0045),and South Asian in 274 of 30776 (3 homozygous) chromosomes (freq. 0.009), increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Consortium Feb 27, 2017). The p.Asp3782Asp variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. A co-occurring pathogenic PKD1 variant (c.7864-1G>T, r.spl?) is identified in 1 individual with ADPKD in our laboratory, increasing the likelihood that p.Asp3782=variant does not have clinical significance. In summary, based on the above information this variant meets our laboratory criteria to be classified as benign. -
