FXTAS is characterized by intention tremor, gait ataxia, executive function deficits, memory issues, and neuropathy.

New NIH grant to study language use as potential predictor of neurodegenerative disorder in FMR1 premutation carriers

A new study will investigate if language differences can predict the development of a neurodegenerative disorder in people that carry a premutation of the gene FMR1.

The FMR1 premutation is of increasing interest to the fragile X syndrome (FXS) community, as questions about a primary premutation phenotype warrant research attention. One hundred FMR1 premutation carrier mothers (mean age = 58; 67 to 138 CGG repeats) of adults with fragile X syndrome were studied with respect to their physical and mental health, and motor and neurocognitive characteristics.

Title: Age at menopause by CGG repeat length Legend: There was a significant curvilinear association between CGG repeat length and age at menopause (b = .003, p < .01). Neither maternal education nor smoking history was significantly associated with age at menopause. The effect remained significant even after the case with 180 CGG repeats was …

Fragile X proteins involved in proper neuron development

Fragile X syndrome is the most common inherited intellectual disability and the greatest single genetic contributor to autism. Unlocking the mechanisms behind fragile X could make important revelations about the brain.
