Invitae RCV001037422 SCV001200833 likely pathogenic Osteogenesis imperfecta type I 2021-09-01 criteria provided, single submitter clinical testing 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. This variant disrupts the c.103+5G nucleotide in the COL1A1 gene. Other variant(s) that disrupt this nucleotide have been determined to be pathogenic (Invitae). This suggests that this nucleotide is clinically significant, and that variants that disrupt this position are likely to be disease-causing. Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). 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: 836318). This variant has been observed in individual(s) with clinical features of osteogenesis imperfecta (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change falls in intron 1 of the COL1A1 gene. It does not directly change the encoded amino acid sequence of the COL1A1 protein. It affects a nucleotide within the consensus splice site of the intron.
