Additional Information:
Clinical Description OMIM |
Worster-Drought et al. (1933) described 9 affected persons in 3 generations. Onset occurred between 40 and 60 years of age with early onset of spasticity with increased deep tendon reflexes and tone. Muscular rigidity was present only late ... |
Molecular genetics OMIM |
Studying amyloid fibrils from a patient described by Plant et al. (1990), Vidal et al. (1999) identified a unique 4-kD protein subunit, which they called ABRI. This highly insoluble peptide is a fragment of a putative type II ... |
