Additional Information:

Description: (OMIM) ALS17 is an adult-onset progressive neurodegenerative disorder with predominantly lower motor neuron involvement, manifest as muscle weakness and wasting of the upper and lower limbs, bulbar signs, and respiratory insufficiency (summary by Cox et al., 2010).
Clinical Description OMIM Parkinson et al. (2006) reported a 75-year-old man with rapidly progressive ALS. At age 74 years, the patient developed bulbar-onset weakness with flaccid dysarthria and tongue fasciculations. He later developed weakness and wasting of the intrinsic hand muscles ...
Molecular genetics OMIM In a 75-year-old man with rapidly progressive ALS, Parkinson et al. (2006) identified a heterozygous mutation in the CHMP2B gene (Q206H; 609512.0003). A second unrelated patient with frontotemporal dementia and ALS had a different heterozygous mutation (I29V; 609512.0005). ...
