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.His570His variant was identified in 8 of 860 proband chromosomes (frequency: 0.009) from individuals or families with ADPKD (Rossetti 2001, Rossetti 2002, Rossetti 2012, Garcia-Gonzalez 2007). The variant was also identified in dbSNP (ID: rs367983387) as â€šÃ„ÃºNAâ€šÃ„Ã¹, Clinvitae (classified as variant of unknown significance by Emory Genetics), and in the ADPKD Mutation Database (classification likely neutral); in the 1000 Genomes Project in 17 of 5000 chromosomes (frequency: 0.0034), in HAP-MAP: HAPMAP-EUR in 15 of 1006 chromosomes (frequency: 0.0149), HAPMAP-AMR in 1 of 694 chromosomes (frequency: 0.0014), HAPMAP-EAS in 1 of 1008 chromosomes (frequency: 0.001), NHLBI GO Exome Sequencing Project (ESP) in 40 of 8462 (frequency: 0.0047) European American, and in 3 of 4308 (frequency: 0.0007) African American alleles. The variant was also identified in the Exome Aggregation Consortium database (March 14, 2016) in 19 of 130 chromosomes (frequency: 0.1462) from a population of European (Finnish) individuals, in 164 (2 homozygous) of 7450 chromosomes (frequency: 0.02201) from a population of European (Non-Finnish) individuals, in 34 of 8056 chromosomes (frequency: 0.0042) from a population of South Asians, and in 3 of 1762 chromosomes (frequency: 0.0017) from a population of African individuals, increasing the likelihood this could be a low frequency benign variant. The variant was not seen in the East Asian, Other or Latino poulations. The variant was identified by our laboratory in a patient with PKD with a co-occurring pathogenic PKD1 variant (c.8388T>G, p.Tyr2796X), increasing the likelihood that the p.His570His variant does not have clinical significance. The p.His570His 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, this variant meets our laboratory criteria to be classified as benign. -
