Invitae | RCV001031409 | SCV001194715 | pathogenic | Charcot-Marie-Tooth disease type 4 | 2021-08-04 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing exon(s) 5 of the PRX gene. This deletion is out-of-frame, and is expected to create a premature translational stop signal and result in an absent or disrupted protein product. Loss-of-function variants in PRX are known to be pathogenic (PMID: 11133365). A similar copy number variant has been observed in individual(s) with Charcot-Marie-Tooth disease (PMID: 28902413). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. For these reasons, this variant has been classified as Pathogenic. |
