The exact cause of ALS is unknown. In some cases, ALS may affect multiple members or different generations of the same family.
Types of ALS
These instances of familial ALS likely have a genetic basis. Changes (mutations) in several genes have been associated with familial ALS. More commonly, there is no familial association. These sporadic ALS cases presently do not have any identifiable cause, but can occasionally be associated with gene changes (mutations).
