Furthermore, we discovered that the chaperone-associated protein Mlf2 co-aggregates with half of the poly-GA inclusions in the spinal cord of GA-CFP mice, but only in 0.3–2.7% of the poly-GA inclusions in the cortex of C9orf72 ALS/FTD patients. The gene discussed is MLF2; the disease is amyotrophic lateral sclerosis.
