Associated features in females with an FMR1 premutation / Anne C. WHEELER in Journal of Neurodevelopmental Disorders, 6-1 (December 2014)
[article]
Titre : Associated features in females with an FMR1 premutation Type de document : Texte imprimé et/ou numérique Auteurs : Anne C. WHEELER, Auteur ; Donald B. Jr BAILEY, Auteur ; Elizabeth BERRY-KRAVIS, Auteur ; J. GREENBERG, Auteur ; M. LOSH, Auteur ; M. MAILICK, Auteur ; M. MILA, Auteur ; J. M. OLICHNEY, Auteur ; L. RODRIGUEZ-REVENGA, Auteur ; S. SHERMAN, Auteur ; L. SMITH, Auteur ; S. SUMMERS, Auteur ; J. C. YANG, Auteur ; Randi J. HAGERMAN, Auteur Article en page(s) : p.30 Langues : Anglais (eng) Mots-clés : FMR1 premutation fragile X health risks Index. décimale : PER Périodiques Résumé : Changes in the fragile X mental retardation 1 gene (FMR1) have been associated with specific phenotypes, most specifically those of fragile X syndrome (FXS), fragile X tremor/ataxia syndrome (FXTAS), and fragile X primary ovarian insufficiency (FXPOI). Evidence of increased risk for additional medical, psychiatric, and cognitive features and conditions is now known to exist for individuals with a premutation, although some features have been more thoroughly studied than others. This review highlights the literature on medical, reproductive, cognitive, and psychiatric features, primarily in females, that have been suggested to be associated with changes in the FMR1 gene. Based on this review, each feature is evaluated with regard to the strength of evidence of association with the premutation. Areas of need for additional focused research and possible intervention strategies are suggested.

Titre : The cognitive neuropsychological phenotype of carriers of the FMR1 premutation Type de document : Texte imprimé et/ou numérique Auteurs : J. GRIGSBY, Auteur ; Kim CORNISH, Auteur ; D. HOCKING, Auteur ; C. KRAAN, Auteur ; J. M. OLICHNEY, Auteur ; S. M. RIVERA, Auteur ; A. SCHNEIDER, Auteur ; S. SHERMAN, Auteur ; J. Y. WANG, Auteur ; J. C. YANG, Auteur Article en page(s) : p.28 Langues : Anglais (eng) Mots-clés : Cognition disorders Executive function Fmr1 Fxtas Fragile X Fragile X premutation Fragile X-associated tremor/ataxia syndrome Index. décimale : PER Périodiques Résumé : The fragile X-associated tremor/ataxia syndrome (FXTAS) is a late-onset neurodegenerative disorder affecting a subset of carriers of the FMR1 (fragile X mental retardation 1) premutation. Penetrance and expression appear to be significantly higher in males than females. Although the most obvious aspect of the phenotype is the movement disorder that gives FXTAS its name, the disorder is also accompanied by progressive cognitive impairment. In this review, we address the cognitive neuropsychological and neurophysiological phenotype for males and females with FXTAS, and for male and female unaffected carriers. Despite differences in penetrance and expression, the cognitive features of the disorder appear similar for both genders, with impairment of executive functioning, working memory, and information processing the most prominent. Deficits in these functional systems may be largely responsible for impairment on other measures, including tests of general intelligence and declarative learning. FXTAS is to a large extent a white matter disease, and the cognitive phenotypes observed are consistent with what some have described as white matter dementia, in contrast to the impaired cortical functioning more characteristic of Alzheimer's disease and related disorders. Although some degree of impaired executive functioning appears to be ubiquitous among persons with FXTAS, the data suggest that only a subset of unaffected carriers of the premutation - both female and male - demonstrate such deficits, which typically are mild. The best-studied phenotype is that of males with FXTAS. The manifestations of cognitive impairment among asymptomatic male carriers, and among women with and without FXTAS, are less well understood, but have come under increased scrutiny.
