Genetic The underlying cause of<unk>  is not clear, but many cases seem to be familial. About half of the cases are due to a genetic mutation and the pattern of inheritance is most consistent with autosomal dominant transmission. No genes have been identified yet, but genetic linkage has been established with several chromosomal regions. Toxins Some environmental factors, including toxins, are also under active investigation, as they may play a role in the disease's cause.
