Description : Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized
by upper and lower motor neuron dysfunction resulting in rapidly progressive paralysis
and death from respiratory failure. The pathologic hallmarks of the disease include
pallor of the corticospinal tract due to loss of motor neurons, presence of ubiquitin-positive
inclusions within surviving motor neurons, and deposition of pathologic TDP43 (TARDBP;
605078) aggregates. Patients with ALS14 may develop frontotemporal dementia (FTD)
(summary by Johnson et al., 2010). See inclusion body myopathy with early-onset Paget
disease and frontotemporal dementia (IBMPFD; 167320), which is also caused by mutation
in the VCP gene and shows some overlapping features. In some families with a VCP mutation,
some family members may have ALS14, and other members may have IBMPFD.;
