Labcorp Genetics (formerly Invitae), Labcorp RCV000703223 SCV000832115 likely pathogenic Ehlers-Danlos syndrome, type 4 2018-07-02 criteria provided, single submitter clinical testing This sequence is a deletion of the first nucleotide in exon 43 and the intron 42 boundary and the insertion of 2 nucleotides (c.3094-10_3094delinsGT). It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with COL3A1-related disease. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in COL3A1 are known to be pathogenic (PMID: 24922459). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
