Conversion disorder in women with the FMR1 premutation [PDF]

American Journal of Medical Genetics Part A, 2009
AbstractWomen with fragile X mental retardation (FMR1) gene premutations (55–200 CGG repeats) were until recently believed to be unaffected. It is now known that up to 8% of older female FMR1 premutation carriers develop fragile X‐associated tremor/ataxia syndrome (FXTAS). Female carriers may also develop primary ovarian insufficiency, thyroid disease,

Psychiatric and Cognitive Features in Italian Women With the FMR1 Premutation: A Comprehensive Assessment Using SCID‐5 and Standardized Cognitive Measures

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Women with the FMR1 premutation (PM) are at increased risk for fragile X‐associated conditions (FXPAC), including cognitive and psychiatric features collectively termed fragile X‐associated neuropsychiatric disorders (FXAND). This study is the first to systematically investigate cognitive and psychiatric features in Italian female premutation ...

Evaluation of the role of FMR1 CGG repeat allele in Parkinson’s disease from the Chinese population

Frontiers in Aging Neuroscience, 2023
ObjectiveThere is controversial evidence that FMR1 premutation or “gray zone” (GZ) allele (small CGG expansion, 45–54 repeats) was associated with Parkinson’s disease (PD).

The role of AGG interruptions in the transcription of FMR1 premutation alleles.

PLoS ONE, 2011
Fragile X associated disorders are caused by a premutation allele in the fragile X mental retardation 1 gene (FMR1) and are hypothesized to result from the toxic effect of elevated levels of expanded FMR1 transcripts.

Tophaceous gout of the nose in a male FMR1 premutation carrier

Clinical Case Reports, 2022
Premutation alleles with 55–200 CGG repeats in FMR1 can lead to fragile X‐associated tremor/ataxia syndrome (FXTAS). In this case study, we report uncontrolled gout in a 68‐year‐old male with FXTAS with multiple sites of involvement including a rare ...

Interaction of FXTAS Family History and College Degree Attainment Predicts Trajectories of Cognitive and Motor Symptoms in FMR1 Premutation Carrier Women

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT The present longitudinal study focuses on FMR1 premutation carrier women during midlife and early old age (n = 115). Bringing together the genetic risk factor of a family history of FXTAS and the environmental protective factor of higher education, the goal of the study was to determine how these factors potentially interact to predict self ...

Predictors of Comorbid Conditions in Women Who Carry an FMR1 Premutation

Frontiers in Psychiatry, 2021
Purpose: Women who carry an FMR1 premutation (PM) can experience two well-established PM-associated disorders: fragile X-associated primary ovarian insufficiency (FXPOI, affects ~20–30% carriers) and fragile X-associated tremor-ataxia syndrome (FXTAS ...

FXTAS and the Spectrum of FMR1 Premutation‐Associated Phenotypes in Latin America: A Scoping Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Fragile X–associated tremor/ataxia syndrome (FXTAS) is a late‐onset neurodegenerative disorder caused by FMR1 premutation expansions (55–200 CGG repeats). Although well described in populations of predominantly European ancestry, FXTAS remains poorly characterized in Latin America due to limited awareness, restricted access to ...
