Study design: Case Report
Abstract: Background: Tuberous sclerosis complex (TSC) is an autosomal dominant neurocutaneous disorder. Despite established genetic causes, missed or late diagnosis remains common in familial cases. This study reports a familial case of TSC to highlight the diagnostic challenges and evaluate the clinical efficacy of everolimus in managing cutaneous and neurologic symptoms. Case presentation: gene in both the patient and the mother: c.848 + 281 (IVS9) C > T. No mutation at this site was detected in the father. Following the diagnosis, the patient received treatment with everolimus. A significant reduction in seizure frequency and improvement in facial angiofibromas were observed during the follow-up period. Conclusion: A heterozygous splicing mutation in the TSC2 gene was identified, confirming the diagnosis of familial TSC. This case underscores the importance of genetic testing in suspected cases to prevent late diagnosis. Furthermore, our findings support the effectiveness of everolimus as a therapeutic option for alleviating TSC-associated neurological and cutaneous manifestations.
