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.

The PKD1 p.Asn1791= variant was identified in 2 of 550 proband chromosomes (frequency: 0.003636) from individuals or families with autosomal dominant polycystic kidney disease (ADPKD) (Rossetti 2002, Rossetti 2012). The variant was also identified in dbSNP (ID: rs143017410) â€šÃ„ÃºWith Benign allele,â€šÃ„Ã¹ ClinVar (as benign by Prevention Genetics), and ADPKD Mutation Database (2x as likely neutral). The variant was not identified in GeneInsight-COGR, LOVD 3.0, and PKD1-LOVD databases. The variant was identified in control databases in 265 of 269328 chromosomes at a frequency of 0.001 increasing the likelihood that this may be a low frequency benign variant in certain populations of origin (Genome Aggregation Consortium Feb 27, 2017), being identified in the following populations: African in 234 of 22952 chromosomes (frequency: 0.0102), Ashkenazi Jewish in 6 of 9984 chromosomes (frequency: 0.00006), Latino in 20 of 34170 chromosomes (frequency: 0.00006), Other in 2 of 6290 chromosomes (frequency: 0.00003), and European Non-Finnish in 3 of 122142 chromosomes (frequency: 0.00002). In addition we cannot be certain that data from control databases is specific to PKD1 and not from one of the six PKD1 pseudogenes. The p.Asn1791= 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. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
