New candidate gene mutations in astrocytoma with seizures.

ABSTRACT: Seizures are a common presenting symptom in astrocytomas, yet the underlying genomic drivers remain incompletely understood. We performed whole-exome sequencing on tumor tissue from 40 patients with astrocytoma (25 with preoperative seizures, 15 without) to explore somatic mutation profiles associated with seizure occurrence. Clinical characteristics, including age, tumor location, volume, and IDH mutation status, did not significantly differ between seizure and non-seizure groups. In the overall cohort, nine genes showed nominal associations with seizures, but none remained significant following correction for multiple comparisons. Stratification by IDH status revealed that CELSR1 mutations were significantly enriched in the seizure group among IDH-wildtype astrocytomas/glioblastomas (6/1
