Abstract:
Objective:To identify pathogenic mutation of TSC1 and TSC2 genes in a patient with long-time misdiagnosis of epilepsy.
Methods:Peripheral blood samples and clinical data of the patient and her 2 parents were collected. Potential mutation of TSC1 and TSC2 genes were detected by direct sequencing.
Results:The patient had frequent episodes of epilepsy in addition with Shagreen patches for 10 years. A frame-shifting mutation c. 2509_2512delAACA was detected in exon 20 of the TSC1 gene. This same mutation was not found in her unaffected parents.
Conclusion:The recurrent frame-shifting mutation c. 2509_2512delAACA (p.Asn837ValfsX11) of the TSC1 gene probably underlies the disease in this patient.
