ABSTRACT
PURPOSE:
EEG anomalies and epilepsy are a not so rare clinical manifestation in patients with Phosphatase and tensin homolog (PTEN) variants. The main aim of this study is to analyze the characteristics of EEG traces, neuroimaging findings and epilepsy to better define the neurological aspects in a set of patients with PTEN variants collected in four Italian Centres. As a secondary aim, we describe the neurodevelopmental profile and the psychiatric comorbidities of this cohort.METHODS:
Patients with PTEN variants, identified by Sanger sequencing or target resequencing, were enrolled. For each subjects, clinical data were retrospectively extracted from medical charts, with a focus on epilepsy and neuroimaging data.RESULTS:
54 patients with PTEN variants were enrolled, with a mean age of 18.8 years. 72.2% have at least one psychiatric diagnosis, being Autism Spectrum Disorder and Intellectual Disability the most frequent diagnosis (29 and 25 cases, respectively). 22 subjects show an abnormal EEG and 8 received a diagnosis of epilepsy, mainly focal epilepsy (7/8), with a mean age at seizure onset of 3.8 years. 3/8 subjects have a drug resistant epilepsy, independently from the underlying neuroimaging pattern. The finding of a Focal cortical dysplasia is significantly associated with both an abnormal EEG (p = 0.02) and the occurrence of seizures (p = 0.002).CONCLUSION:
EEG should be taken into consideration in the first-line diagnostic flowchart of subjects with PTEN variants. The onset of a focal epilepsy, independently from its response to antiepileptic drugs, highly recommends to carry out a neuroimaging exam.Palabras clave
