Invitae | RCV000633039 | SCV000754251 | likely pathogenic | Spastic paraplegia | 2017-12-02 | criteria provided, single submitter | clinical testing | 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. Different truncation variants that lie downstream of this variant have been reported in individuals affected with Pelizaeus-Merzbacher-like disease (PMID: 18094336, 20513814). This suggests that deletion of this region of the GJC2 protein is causative of disease. This variant has not been reported in the literature in individuals with GJC2-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change results in a premature translational stop signal in the GJC2 gene (p.Tyr47*). While this is not anticipated to result in nonsense mediated decay, it is expected to delete the last 393 amino acids of the GJC2 protein. |
