Illumina Clinical Services Laboratory,Illumina RCV001121237 SCV001279806 uncertain significance Xeroderma pigmentosum, group F 2017-04-27 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Baylor Genetics RCV001332584 SCV001524956 uncertain significance XFE progeroid syndrome 2019-05-09 criteria provided, single submitter clinical testing This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868].

Department of Pathology and Laboratory Medicine,Sinai Health System RCV001354835 SCV001549546 uncertain significance not provided no assertion criteria provided clinical testing The ERCC4 p.Ile706Thr variant was not identified in the literature nor was it identified in Cosmic. The variant was identified in dbSNP (ID: rs1800069), LOVD 3.0 and ClinVar (classified as uncertain significance by Genetic Services Laboratory, University of Chicage, and as likely benign by Invitae). The variant was identified in control databases in 366 of 268308 chromosomes (1 homozygous) at a frequency of 0.001364 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: European (non-Finnish) in 283 of 118142 chromosomes (freq: 0.002395), Other in 12 of 6702 chromosomes (freq: 0.001791), Latino in 50 of 35108 chromosomes (freq: 0.001424), European (Finnish) in 11 of 25108 chromosomes (freq: 0.000438), African in 9 of 23614 chromosomes (freq: 0.000381) and Ashkenazi Jewish in 1 of 9858 chromosomes (freq: 0.000101), but was not observed in the East Asian or South Asian populations. The p.Ile706 residue is conserved in mammals but not in more distantly related organisms and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the variant may impact the protein; however, this information is not predictive enough to assume pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
