Of note, comparative analysis of mis-spliced genes did not show a significant overlap between brain regions, and only 14 genes were mis-spliced in all four regions (AKIP1, C11orf73, FLOT1, KIAA1841, NCALD, PDE4DIP, POMT1, PREPL, PR11-274B21.1, SORBS1, TPD52L1, VEZT, ZHX3, and ZNF638), suggesting a possibility of mis-splicing events occurring rather in a random manner.
