    AbstractAutopsy of patients with sporadic amyotrophic lateral sclerosis (ALS) rarely provides clues to a genetic etiology. We studied a 66-year-old woman who developed progressive weakness, fasciculations and upper motor neuron signs 1 year after mastectomy and chemotherapy for a breast carcinoma. She died 14 months after the onset of neurological symptoms. Autopsy showed characteristic features of ALS but also with posterior column degeneration and conglomerate hyaline inclusions. These features suggested a mutation of SOD1 mutation although no other family members were affected. DNA analysis of autopsy tissue indicated an I113T SOD1 mutation.
