Labcorp Genetics (formerly Invitae), Labcorp RCV003031902 SCV003328837 pathogenic Cerebral cavernous malformation 2 2022-03-12 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with CCM2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Tyr221*) in the CCM2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CCM2 are known to be pathogenic (PMID: 18300272, 24689081).
