An overview of recently proposed ALS genes that were identified based on rare genetic variants (TBK1, CHCHD10, TUBA4A, CCNF, MATR3, NEK1, C21orf2, ANXA11, TIA1) and their potential relevance to the genetic etiology of frontotemporal dementia have also been described [10]. This evidence concerns the gene TBK1 and frontotemporal dementia.
