We have used an antibody to detect the poly‐GA DPR as it has been demonstrated to be the most prevalent in a series of both FTLD‐TDP and MND‐TDP cases harbouring the C9orf72 expansion [4], as well as the main aggregating species of DPR in FTLD‐UPS cases with C9orf72 repeat expansions [6]. The gene discussed is C9orf72; the disease is mild neurocognitive disorder.
