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.

PKD1, c.9569-13T>C, (Alias: IVS27-13T>C), Heterozygous, Benign The PKD1 c.9569-13T>C variant was identified in 22 of 328 proband chromosomes (frequency: 0.067) from individuals or families with ADPKD or renal disease, and was not identified in 100 control chromosomes from healthy individuals (Bataille 2011, Garcia-Gonzalez 2007, Rossetti 2002). All the above studies have identified the variant as a polymorphism. The c.9569-13T>C variant was identified in the dbSNP (ID: rs11248911) with unknown clinical significance with a minor allele frequency 0.1556 (779 of 5000 chromosomes in 1000 Genome Project). The variant was not identified In the NHLBI Exome Sequencing Project (Exome Variant Server). The variant was identified in Exome Aggregation Consortium (March 14, 2016) in 5596 of 114186 chromosomes (frequency: 0.04901) or 330 of 6146 of European (Finnish), 2393 of 62978 European (Non-Finnish), 2033 of 8090 African, 193 of 11226 Latino, 601 of 16298 South Asians, 3 of 8592 East Asians and 43 of 856 Other populations. The variant was identified in PKD Mutation Database and classified as likely neutral and not predicted to alter splicing. The c.9569-13T>C variant occurs outside of the splicing consensus sequence and 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. -
