Background: Increased availability of genetic testing has led to increased burden of follow up of variants of uncertain significance (VUS). As of January 2025, 327 VUS were identified patients at BC Children’s Hospital. We propose a pipeline to triage and follow up of patients with identified VUS to clarify diagnosis through paternal testing. Methods: Of the 327 patients with VUS, 13 patients with high clinical suspicion for a genetic disorder were identified by their neurologist. Initial chart review for each patient was performed. Clinical phenotype data and the patient’s variant were inputted into the online tool Franklin. This program generates a variant interpretation based on 17/ 28 criteria in ACMG scoring. For each patient the variant would be assumed to be de novo in order to determine if parental testing could change variant classification. Results: 5/13 of the patients had suggested reclassification of variants. 6/13 of the patients would have reclassification of variant to likely pathogenic/pathogenic if the variant was found to be de novo, suggesting a need for paternal testing. Conclusions: This highlights a novel clinical pipeline to improve expediency and triaging of VUS reclassification for paternal testing in epilepsy genomics.
