RCV001354014 | SCV000592821 | benign | Bile duct cancer | no assertion criteria provided | clinical testing | The PKD1 p.Ser2766Ser variant was identified in 3 of 246 proband chromosomes (frequency: 0.012) from Japanese, Slovenian and American individuals or families with ADPKD, co-occurring with a pathogenic splicing PKD1 variant (c.8228-2delAG) in 1 Japanese individual (Garcia-Gonzalez 2007, Vouk 2006, Inoue 2002). The variant was also identified by our laboratory in an individual with ADPKD, co-occurring with a pathogenic PKD1 variant (c.2215C>T), increasing the likelihood that the p.Ser2766Ser variant does not have clinical significance. The variant was also identified in dbSNP (ID: rs145850037) as “NA”, and the ADPKD Mutation Database (classification likely neutral) and in the ClinVar database classified as Likely Benign by Prevention Genetics, but was not found in PKD1-LOVD, Clinvitae, GeneInsight COGR, MutDB and PKD1-LOVD 3.0. This variant was identified in the 1000 Genomes Project in 5 of 5000 chromosomes (frequency: 0.001), NHLBI GO Exome Sequencing Project in 21 of 8552 European American alleles (frequency: 0.0025) and in 5 of 4352 African American alleles (frequency: 0.0011), the Exome Aggregation Consortium database (August 8, 2016) in 118 of 115912 chromosomes (freq. 0.0010)) in the following populations: European (Non-Finnish) in 95 of 63278 chromosomes (freq. 0.0015), African in 11 of 8940 chromosomes (freq. 0.0012), Latino in 9 of 11392 chromosomes (freq. 0.00079), South Asian in 3 of 16460 chromosomes (freq. 00018), but was not seen in East Asian, Finnish, or Other populations; increasing the likelihood this could be a low frequency benign variant. The p.Ser2766Ser 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. In addition, 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's criteria to be classified as benign. |
