Deep tissue sequencing improves genetic diagnostic yield in focal cortical dysplasia

Breana Galea, Joshua Reid, Samuel Gooley, Tom Witkowski, Tara Lane, Sian Macdonald, Timothy E. Green, Zimeng Ye, Thiuni N. Adikari, Kristian John Bulluss, Saul Alator Mullen, Caitlin A. Bennett, Brialie Forster, Gabi Bradshaw, Wendi Lin, , Michael S. Hildebrand

This study uses deep sequencing to identify genetic variants in focal cortical dysplasias, finding pathogenic variants in 71% of cases and highlighting the importance of somatic variants in FCDIIb.

Cell-type-informed genotyping of mosaic focal epilepsies reveals cell-autonomous and non-cell-autonomous disease-associated transcriptional programs

Sara Bizzotto, Maya Talukdar, Edward Stronge, Rosita B. Ramirez, Yingxi Yang, August Yue Huang, Qiwen Hu, Yingping Hou, Norma K. Hylton, Benjamin Finander, Ashton Tillett, Zinan Zhou, Brian H. Chhouk, Alissa M. D’Gama, Edward Yang, , Christopher A. Walsh

This study uses snRNA-seq and a new method called GO-TEN to analyze mosaic genetic variants in focal cortical dysplasia, revealing cell-autonomous and non-cell-autonomous transcriptional changes associated with epilepsy.
