RCV001291898 | SCV000592772 | benign | Polycystic kidney disease | no assertion criteria provided | clinical testing | PKD1, EXON15, c.4264G>A, p.Ala1422Thr, (Alias c.4475G>A), Heterozygous, Benign The PKD1 p.Ala1422Thr variant was identified in 3 of 864 proband chromosomes (frequency: 0.003) from individuals or families with ADPKD, and was not identified in 242 control chromosomes from healthy individuals (Rossetti 2007, Rossetti 2012). The variant was also identified in dbSNP (ID: rs140980374) “With clinical significance allele not available”, in 1000 Genomes Project in 22 of 5000 chromosomes (frequency: 0.004), in NHLBI GO Exome Sequencing Project (ESP) in 72 of 8592 European American (frequency: 0.008) and 9 in 4394 (frequency: 0.002) African American alleles. This variant was identified in the Exome Aggregation Consortium database (March 2016) in 713 (5 homozygous) of 118566 chromosomes (freq. 0.006) in the following populations: other in 10 of 880 chromosomes (freq. 0.01), European (Non-Finnish) in 565 of 64594 chromosomes (freq. 0.009), South Asian in 76 of 16504 chromosomes (freq. 0.005), Latino in 45 of 11538 chromosomes (freq. 0.004), Finnish in 7 of 6602 chromosomes (freq. 0.001), and African in 10 of 9854 chromosomes (freq. 0.001), but was not seen in the East Asian populations, increasing the likelihood this could be a low frequency benign variant. However we cannot be certain that variant data from control databases is specific to PKD1 and not from one of the six PKD1 pseudogenes. Furthermore, the variant is listed in the GeneInsight COGR database as benign, as likely neutral in the ADPKD Mutation Database, and listed with no classification in the PKD1-LOVD 3.0 database. The p.Ala1422 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. Furthermore, the variant amino acid “Threonine” is present in macaque, increasing the likelihood that this variant does not have clinical significance. Computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein. 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. The variant was observed as co-occurring with another pathogenic variant in one individual identified by our laboratory, increasing the likelihood this variant does not have clinical significance. In summary, based on the above information, this variant is classified as benign. | |
