Update and recommendations on genetic testing for amyotrophic lateral sclerosis in clinical practice: a Brazilian expert view.

Abstract excerpt

Amyotrophic lateral sclerosis (ALS) is a complex and progressive neurodegenerative disorder characterized by the degeneration of both upper and lower motor neurons. Although most ALS cases occur sporadically, without a known family history of the disease, genetic factors play a major role in its pathogenesis through monogenic, oligogenic, or polygenic mechanisms. It is estimated that 10-15% of ALS cases occur in...
