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.Ala3456Ala variant was identified in 4 of 534 proband chromosomes (frequency: 0.007) from individuals or families with ADPKD or renal disease, and was not identified in 100 control chromosomes from healthy individuals (Bataille 2011, Rossetti 2012). These studies have both identified the variant as a polymorphism. The p.Ala3456Ala variant was identified in the dbSNP (ID: rs7194935) with “With Benign allele” with a minor allele frequency of 0.03 (152 of 5000 chromosomes in 1000 Genome Project). In the NHLBI Exome Sequencing Project (Exome Variant Server), the variant was identified in 5 of 8594 alleles (frequency: 0.0005) in the European Americans and 423 of 4392 alleles in African Americans (Frequency: 0.1). The variant was identified in the Exome Aggregation Consortium database (August 08, 2016) in 1034 of 114508 chromosomes (frequency: 0.009 with 45 homozygotes) in the following populations: African in 933of 9530 chromosomes (frequency: 0.1), Latino in 53 of 11138 chromosomes (frequency: 0.005), European (Non-Finnish) in 40 of 62920 chromosomes (frequency: 0.0006), South Asian in 3 of 16084 chromosomes (frequency: 0.0002) and Other in 5 of 820 chromosomes (frequency 0.006) but was not seen in East Asian and Finnish populations, increasing the likelihood this could be a low frequency benign variant. The p.Ala3456Ala variant is not expected to have clinical significance because it does not result in a change of amino acid. The 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. -
