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 c.288-11G>C variant was identified in a ADPKD mutational analysis study of PKD1 and PKD2 genes in Chinese individuals or families with ADPKD, and was present in 4 of 200 control chromosomes (frequency: 0.020) from healthy individuals (Yu 2011). The variant was identified in the ADPKD Mutation Database (classification likely neutral), but was not identified in dbSNP, 1000 Genomes, NHLBI GO Exome Sequencing Project, the Exome Aggregation Consortium (March 2016), Clinvitae, ClinVar, GeneInsight COGR, PKD1-LOVD, and PKD1-LOVD 3.0 databases. The variant occurs outside of the splicing consensus sequence and 1 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. 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. -
