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.3006G>C variant was not identified in the literature nor was it identified in the Clinvitae, ClinVar, GeneInsight COGR, MutDB, PKD1-LOVD, and PKD1-LOVD 3.0 databases. The variant was identified in dbSNP (ID: rs143013095) as “N/A”, and the ADPKD Mutation Database (classified as likely neutral by Athena Diagnostics). This variant was also identified in the 1000 Genomes Project in 2 of 5000 chromosomes (frequency: 0.0004), NHLBI GO Exome Sequencing Project in 8 of 8600 European American alleles, the Exome Aggregation Consortium database (August 8, 2016) in 136 of 119208 chromosomes (freq. 0.001) in the following populations: European in 122 of 65136 chromosomes (freq. 0.002), Finnish in 11 of 6556 chromosomes (freq. 0.002), Latino in 2 of 11502 chromosomes (freq. 0.0002) and Other in 1 of 880 chromosomes (freq. 0.001), although this low number of observations and low frequency is not substantive enough to determine the prevalence of the variant in the general population and its relationship to disease. The p.Val1002Val 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. The variant occurs outside of the splicing consensus sequence and 3 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing. However, this information is not predictive enough to assume 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. -
