An Autopsy Case With Fragile X‐Associated Tremor/Ataxia Syndrome Presenting Intranuclear Inclusion Bodies Mainly in the Limbic System

Neuropathology, Volume 46, Issue 2, April 2026.
ABSTRACT Fragile X‐associated tremor/ataxia syndrome (FXTAS) is a neurodegenerative disorder characterized by a late onset and slow progression caused by a premutation (55–200 CGG repeat) in the fragile X mental retardation (FMR1) gene. Here, we report the case of a Japanese patient with FXTAS which is the first case autopsied in Japan. The patient was
