Invitae | RCV000532770 | SCV000631896 | likely pathogenic | Propionic acidemia | 2016-08-22 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing exons 13-20 of the PCCA gene. This change leads to an in-frame deletion of 260 amino acids. A deletion of exons 13-20 has been reported to co-occur with another likely pathogenic or pathogenic PCCA variant in an individual affected with propionic acidemia in the literature (PMID: 19157943) as well as one individual tested at Invitae. Loss of function truncating variants in PCCA are known to be pathogenic (PMID: 15464417). This deletion is expected to impair protein function. However, the severity of impact has not been determined by functional studies. For these reasons, this variant has been classified as Likely Pathogenic. |
