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 ...
