Findings

This mutation was identified in an English family referred to as the Yorkshire kindred. It was found in a pair of siblings with aggressive early onset hereditary tauopathy, who presented with acute respiratory failure. The parents were unaffected (at least at the time of assessment) despite carrying the S352L mutation. The disease is thought to have a recessive mode of inheritance, but may also be a dominant disorder with reduced penetrance (Nicholl et al., 2003).

Neuropathology

Extensive tau neuropathology was observed at autopsy (Nicholl et al., 2003).

Biological Effect

Recombinant S352L tau exhibited reduced microtubule binding and accelerated filament formation (Nicholl et al., 2003).
