Somatic Mutations in Surgical Epilepsy Tissue
+61 3 9035 7143
Somatic mutagenesis, occurring post-fertilization, may play an important role in causation of the severe end of the focal epilepsy spectrum. To unravel this contribution, we are studying two privileged resources. First, a unique set of 50 patients with focal epilepsy refractory to anti-epileptic drugs who have had epilepsy surgery, facilitate an exciting new approach to this problem. Second, we are taking advantage of our large biobank of 150 formalin-fixed paraffin-embedded (FFPE) brain specimens resected from patients with focal epilepsy over the last 10 years. We are applying molecular inversion probe (MIP) gene capture panel (Figure 4) and exome sequencing (for DNA), and RNA sequencing, respectively, which are well established techniques for deep sequencing fresh-frozen tissue in our hands.
