Invitae RCV002233483 SCV000762018 pathogenic Autosomal dominant epilepsy with auditory features 2020-03-06 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. A different truncation (p.Ile547Asnfs*8) that lies downstream of this variant has been determined to be likely pathogenic (PMID: 11810107, 18711109, 15857855). This suggests that deletion of this region of the LGI1 protein is causative of disease. This variant has not been reported in the literature in individuals with LGI1-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 LGI1 gene (p.Thr390Lysfs*2). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 168 amino acids of the LGI1 protein.
