Invitae RCV001225334 SCV001397610 pathogenic Osteogenesis imperfecta type I 2019-10-31 criteria provided, single submitter clinical testing 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. For these reasons, this variant has been classified as Pathogenic. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in COL1A1 are known to be pathogenic (PMID: 7942841, 9295084, 9443882). This variant has been observed in individual(s) with osteogenesis imperfecta type 1 (PMID: 22206639). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (ExAC no frequency). This sequence change affects an acceptor splice site in intron 42 of the COL1A1 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product.
