Invitae | RCV001033156 | SCV001196463 | likely pathogenic | Propionic acidemia | 2021-08-04 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing exon(s) 5-12 of the PCCA gene. This variant would be expected to be in-frame, preserving the integrity of the reading frame. This variant has not been reported in the literature in individuals affected with PCCA-related conditions. This variant disrupts the p.Arg288 amino acid residue in PCCA. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 7915138, 20493181, 20725044, 27227689). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. |
