Labcorp Genetics (formerly Invitae), Labcorp RCV003044106 SCV003343396 uncertain significance Cerebral cavernous malformation 2 2022-04-15 criteria provided, single submitter clinical testing This sequence change falls in intron 2 of the CCM2 gene. It does not directly change the encoded amino acid sequence of the CCM2 protein. It affects a nucleotide within the consensus splice site. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individual(s) with cerebral cavernous malformations (Invitae). Variants that disrupt 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. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
