ALS phenotypes with mutations in CHMP2B (charged multivesicular body protein 2B)
Neurology, 2006•AAN Enterprises
Mutation in the CHMP2B gene has been implicated in frontotemporal dementia. The authors
screened CHMP2B in patients with ALS and several cohorts of control samples. They
identified mutations (Q206H; I29V) in two patients with non-SOD1 ALS. Neuropathology of
the Q206H case showed lower motor neuron predominant disease with ubiquitylated
inclusions in motor neurons. Antibodies to p62 (sequestosome 1) showed novel
oligodendroglial inclusions in the motor cortex.
