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.Ser1125Servariant was identified in 10.8% of 95064 control alleles in the Exome Aggregation Consortium (March 14, 2016). This variant was identified by our laboratory with a co-occurring pathogenic PKD1 variant (c.11798_11810del, p.Leu3933ArgfsX8), in a patient with PKD increasing the likelihood that the p.Ala3512Val variant does not have clinical significance. According to ACMG guidelines for variant classification based on allele frequency, category BA1, this variant is considered benign and has not been further reviewed (Richards 2015). -
