Invitae RCV000799168 SCV000938820 pathogenic Propionyl-CoA carboxylase deficiency 2018-12-31 criteria provided, single submitter clinical testing This sequence change results in a premature translational stop signal in the PCCB gene (p.Glu480Cysfs*26). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 60 amino acids of the PCCB protein. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with PCCB-related conditions. Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the affected amino acid(s) is currently unknown. This variant disrupts the C-terminus of the PCCB protein. Other variant(s) that disrupt this region (p.Arg499*) have been determined to be pathogenic (PMID: 8295402, 12007220, 12189489, 11136555). This suggests that variants that disrupt this region of the protein are likely to be causative of disease. For these reasons, this variant has been classified as Pathogenic.
