Having established these 20 cases as representative of the hnRNP H gradient, we used the motor cortex fractions derived from them for WB for three other ALS/FTD-implicated hnRNPs: TDP-43, FUS (also known as hnRNP P2), and hnRNP A1 (Figure 3d). Here, HNRNPH2 is linked to amyotrophic lateral sclerosis.
