• brainstem neurons exhibit ubiquitin inclusions and astrogliosis unlike in wild-type mice
• in the ventral horn and brainstem neurons
• rare with TARDBP co-localization
• mice exhibit marked astrogliosis compared with wild-type mice
• ventral horn neurons exhibit prominent ubiquitin positive cytoplasmic inclusions unlike in wild-type mice
• however, no pale amorphous cyto-architectural abnormalities observed in early onset severe founders that fail to exhibit germline transmission

• mice exhibit late onset, progressive motor defects compared with wild-type mice
• progressive
• progressive

• quadriceps muscle exhibits atrophy and angular fibers consistent with denervation changes compared with wild-type mice
• in the quadriceps muscle
• in the hindlimb
