Invitae RCV001039589 SCV001203123 pathogenic Osteogenesis imperfecta type I 2023-07-12 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 838106). Disruption of this splice site has been observed in individuals with clinical features of osteogenesis imperfecta (PMID: 9443882; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change affects an acceptor splice site in intron 25 of the COL1A1 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site 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).
