Labcorp Genetics (formerly Invitae), Labcorp RCV002014339 SCV002301961 uncertain significance Cerebral cavernous malformation 2 2021-01-08 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with CCM2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change affects codon 146 of the CCM2 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the CCM2 protein.
