RCV003014779 | SCV003316036 | pathogenic | Osteogenesis imperfecta type I | 2022-04-12 | criteria provided, single submitter | clinical testing | This sequence change affects a donor splice site in intron 2 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). This variant is not present in population databases (gnomAD no frequency). Disruption of this splice site has been observed in individuals with clinical features of osteogenesis imperfecta (Invitae). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. |
