The general, and cross-supportive, outcome was that all FTD-genes are indeed expressed in brain: for the pure FTD-genes, MAPT, GRN, CHMP2B, CTSC, HLA-DRA and TMEM106B showed moderate to high expression levels across brain tissues throughout the lifespan of an individual, whilst, comparatively, expression levels for RAB38, BTNL2 and HLA-DRB5 appeared to be lower. The gene discussed is TMEM106B; the disease is frontotemporal dementia.
