Labcorp Genetics (formerly Invitae), Labcorp RCV001906376 SCV002176966 pathogenic Beckwith-Wiedemann syndrome 2021-11-05 criteria provided, single submitter clinical testing This variant disrupts a region of the CDKN1C protein in which other variant(s) (p.Arg282*) have been determined to be pathogenic (PMID: 19386358, 26077438; SOURCE: 10424811). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with CDKN1C-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the gnomAD database. This sequence change creates a premature translational stop signal (p.Pro204Argfs*68) in the CDKN1C gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 113 amino acid(s) of the CDKN1C protein.
