Fragile X syndrome and fragile X-associated disorders
Fragile X syndrome (FXS) is caused by a full mutation on the FMR1 gene and a subsequent lack of FMRP, the protein product of FMR1. FMRP plays a key role in regulating the translation of many proteins involved in maintaining neuronal synaptic connections; its deficiency may result in a range of intellectual disabilities, social deficits, psychiatric problems, and dysmorphic physical features. A ...
متن کاملEarly Onset of Fragile X Associated Tremor and Ataxia Syndrome: A Case Report from Iran
Background: Different alleles of Fragile X Mental Retardation1 (FMR1) gene with separate molecular etiologies cause Fragile X Syndrome (FXS) and Fragile X-associated Tremor and Ataxia Syndrome (FXTAS). Premutation alleles with 55 to 200 repeats in the FMR1 gene lead to FXTAS. It is carried by 1 in 209 women and 1 in 430 men. FXTAS commonly appears in 50- to 70-year-old adults. Case Presentatio...
متن کاملFragile X-associated tremor/ataxia syndrome (FXTAS).
Carriers of fragile X mental retardation 1 (FMR1) premutation alleles (55 to 200 CGG repeats) are generally spared the more serious neurodevelopmental problems associated with the full-mutation carriers (>200 repeats) of fragile X syndrome. However, some adult male premutation carriers (55-200 repeats) develop a neurological syndrome involving intention tremor, ataxia, dementia, parkinsonism, a...
متن کاملFragile X syndrome and associated disorders.
The past decades have witnessed staggering advances in the fields of molecular genetics, cognitive neuroscience, neuropsychiatry, and brain imaging. Collectively, these findings have pushed forward a new generation of research aimed at exploring the dynamic interplay between gene expression, developmental brain pathways, and neurocognitive profiles beginning in infancy and moving across the lif...
متن کاملFragile X-associated tremor/ataxia syndrome.
Fragile X-associated tremor/ataxia syndrome (FXTAS) is a hereditary neurodegenerative disorder caused by a mutation on the X chromosome. The major signs and symptoms are tremor, ataxia and parkinsonism. Up to one in 2 000 persons over 50 years of age will develop the syndrome. There is reason to believe that too few individuals in Norway undergo testing for this condition.
