Illumina Laboratory Services, Illumina	RCV000986805	SCV001292700	likely benign	Xeroderma pigmentosum group B	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). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

Department of Pathology and Laboratory Medicine, Sinai Health System	RCV000861013	SCV001549770	likely benign	not provided		no assertion criteria provided	clinical testing	The ERCC3 p.Ser640Leu variant was not identified in the literature but was identified in dbSNP (ID: rs4150521) and ClinVar (classified as benign by Invitae; likely benign by Mendelics for Xeroderma pigmentosum, complementation group b and uncertain significance by CeGaT Praxis fuer Humangenetik Tuebingen). The variant was identified in control databases in 607 of 268178 chromosomes (2 homozygous) at a frequency of 0.002263 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 (Finnish) in 182 of 25100 chromosomes (freq: 0.007251), Other in 32 of 6702 chromosomes (freq: 0.004775), Latino in 103 of 35102 chromosomes (freq: 0.002934), European (non-Finnish) in 257 of 118038 chromosomes (freq: 0.002177), Ashkenazi Jewish in 12 of 9854 chromosomes (freq: 0.001218), African in 12 of 23604 chromosomes (freq: 0.000508) and South Asian in 9 of 30526 chromosomes (freq: 0.000295), but was not observed in the East Asian population. The p.Ser640 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 1 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign.
