Fragile X syndrome in children [PDF]

open access: yesColombia Medica, 2023
Fragile X syndrome is caused by the expansion of CGG triplets in the FMR1 gene, which generates epigenetic changes that silence its expression. The absence of the protein coded by this gene, FMRP, causes cellular dysfunction, leading to impaired brain development and functional abnormalities.

Impaired perceptual learning in a mouse model of Fragile X syndrome is mediated by parvalbumin neuron dysfunction and is reversible. [PDF]

open access: yes, 2018
To uncover the circuit-level alterations that underlie atypical sensory processing associated with autism, we adopted a symptom-to-circuit approach in the Fmr1-knockout (Fmr1-/-) mouse model of Fragile X syndrome.

Fragile X syndrome [PDF]

open access: yesBiological Psychiatry, 1995
Fragile X syndrome is the most important X-linked etiology of mental retardation and developmental disability currently known. Accumulating evidence also indicates that male and female carriers of the fragile X genetic abnormality demonstrate a relatively specific pattern of psychiatric disturbance.

Experimental approaches towards therapeutic interventions for fragile X syndrome [PDF]

open access: yes, 2010
Fragile X syndrome (FXS) is one of the most common inherited forms of intellectual disability. It affects on average 1/4000 males and 1/7000 females. FXS was described for the first time in 1943 by Martin and Bell.

Pharmacological Rescue of Synaptic Plasticity, Courtship Behavior, and Mushroom Body Defects in a Drosophila Model of Fragile X Syndrome [PDF]

open access: yes, 2005
SummaryFragile X syndrome is a leading heritable cause of mental retardation that results from the loss of FMR1 gene function. A Drosophila model for Fragile X syndrome, based on the loss of dfmr1 activity, exhibits phenotypes that bear similarity to ...

Rapidly Progressing Neurocognitive Disorder in a Male with FXTAS and Alzheimer's Disease. [PDF]

open access: yes, 2020
Fragile X-associated tremor/ataxia syndrome (FXTAS) is a neurodegenerative disorder that usually begins in the early 60s and affects carriers of premutation expansion (55-200 CGG repeats) of the fragile X mental retardation 1 (FMR1) gene.
