Labcorp Genetics (formerly Invitae), Labcorp RCV002651700 SCV003525247 pathogenic not provided 2022-07-06 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Thr270Aspfs*10) in the COL7A1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in COL7A1 are known to be pathogenic (PMID: 16971478). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with autosomal recessive dystrophic epidermolysis bullosa (PMID: 12485454). This variant is also known as c.806insT. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. For these reasons, this variant has been classified as Pathogenic.
