Similarly, motor neurone type symptomology is also variably associated with several fFTD‐implicated genes, particularly C9orf72, and can lead to an overlapping syndrome of FTD‐related amyotrophic lateral sclerosis (FTD‐ALS) (Greaves & Rohrer, 2019; Turner et al., 2017). This evidence concerns the gene C9orf72 and frontotemporal dementia.
