Department of Pathology and Laboratory Medicine,Sinai Health System RCV001358605 SCV001554391 uncertain significance not provided no assertion criteria provided clinical testing The COL7A1 p.Val211Ile variant was not identified in the literature nor was it identified in ClinVar or LOVD 3.0. The variant was identified in dbSNP (ID: rs557797952) and Cosmic (FATHMM prediction: pathogenic; score=0.7). The variant was also identified in control databases in 4 of 251358 chromosomes at a frequency of 0.000016 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: East Asian in 3 of 18392 chromosomes (freq: 0.000163) and South Asian in 1 of 30606 chromosomes (freq: 0.000033), but was not observed in the African, Latino, Ashkenazi Jewish, European (Finnish), European (non-Finnish) or Other populations. The p.Val211 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 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.
