I. OFFICIAL DISEASE CLASSIFICATION

Fragile X-associated tremor/ataxia syndrome belongs to SCF Clinical Domains C7 (Neurologic Medicine), C1 (Genomic Medicine), C14 (Genetic Medicine), C13 (Neurodegenerative Biology), and C2 (Cellular Signaling Biology).

II. CLINICAL DEFINITION

Fragile X-associated tremor/ataxia syndrome is a late-onset neurodegenerative disorder occurring primarily in carriers of FMR1 premutation alleles characterized by:

• Intention tremor
• Cerebellar ataxia
• Cognitive decline
• Peripheral neuropathy
• Parkinsonian features
• Autonomic dysfunction

Primary affected systems:

• Cerebellum
• Brainstem
• Cerebral white matter
• Basal ganglia
• Peripheral nervous system
• Neuroglial support networks

Associated conditions:

• Fragile X syndrome
• Spinocerebellar degeneration

III. MAJOR CLASSIFICATIONS

A. Classical FXTAS

B. Male FXTAS

C. Female FXTAS

D. FXTAS with Cognitive-Dominant Presentation

Associated condition:

• Dementia

IV. CORE SCF ETIOPATHOGENIC THESIS

Within the Synergistic Compatibility Framework (SCF), FXTAS represents a systems-level collapse of:

• Neural information-processing harmonics
• RNA regulatory integrity
• Cerebellar synchronization networks
• White matter communication pathways
• Neuroenergetic homeostasis

SCF interprets FXTAS as a decentralized neural communication disorder in which toxic RNA species progressively disrupt neuronal signaling, glial support systems, and long-range brain network synchronization.

XX. SCF LAYMAN’S SUMMARY

Fragile X-associated tremor/ataxia syndrome (FXTAS) is a late-onset neurodegenerative disorder affecting some individuals who carry an FMR1 premutation. Unlike Fragile X syndrome, which is caused by a full mutation, FXTAS results primarily from toxic accumulation of abnormal FMR1 messenger RNA. This leads to tremor, balance problems, cognitive decline, neuropathy, and progressive brain white matter degeneration. SCF interprets FXTAS as a systems-level neural information-processing disorder involving RNA toxicity, mitochondrial stress, cerebellar dysfunction, white matter degeneration, and loss of synchronized neural communication.
