RCV000499868 | SCV000592782 | benign | Polycystic kidney disease | no assertion criteria provided | clinical testing | The PKD1 p.Thr1773Ile variant was not identified in the literature nor was it identified in the Clinvitae, ClinVar, MutDB, PKD1-LOVD and PKD1-LOVD 3.0 databases. The variant was identified in dbSNP (ID: rs140162759) as “NA” with a mean allele frequency of 0.0018 (9 of 5000 chromosomes) in the 1000 Genomes Project; NHLBI GO Exome Sequencing Project in 9 of 8588 European American alleles and not found in African Americans, the Exome Aggregation Consortium database (March 14, 2016) in 290 (3 homozygous) of 118260 chromosomes (freq. 0.002452) in the following populations: South Asian in 234 of 16450 chromosomes (freq. 0.01422), European (Non-Finnish) in 51 of 64804 chromosomes (freq. 0.000787), Latino in 3 of 11454 chromosomes (freq. 0.0002619), African in 1 of 10028 chromosomes (freq. 0.00009972 and Other in 1 of 862 chromosomes (freq. 0.00116), but was not seen in East Asian and Finnish populations, increasing the likelihood this could be a low frequency benign variant. In addition we cannot be certain that data from control databases is specific to PKD1 and not from one of the six PKD1 pseudogenes. The variant was identified in GeneInsight COGR (benign) and the ADPKD Mutation Database (likely neutral). The p.Thr1773 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant amino acid Isoleucine is present in Ciona intestinalis, increasing the likelihood that this variant does not have clinical significance. 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, this variant is classified as benign. | |
