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 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 کاملAdvances in understanding fragile X syndrome and related disorders.
PURPOSE OF REVIEW Fragile X syndrome is the most common form of inherited intellectual disability. Over the past 2 decades, insights into the cause of this disease have increased tremendously. This review will highlight recent discoveries with an emphasis on biochemical pathways affected in the disorder that are potentially amenable to treatment. RECENT FINDINGS Recent work in the field demon...
متن کاملFragile X spectrum disorders.
The fragile X mental retardation 1 gene (FMR1), which codes for the fragile X mental retardation 1 protein (FMRP), is located at Xp27.3. The normal allele of the FMR1 gene typically has 5 to 40 CGG repeats in the 5' untranslated region; abnormal alleles of dynamic mutations include the full mutation (> 200 CGG repeats), premutation (55-200 CGG repeats) and the gray zone mutation (45-54 CGG repe...
متن کاملThe fragile X syndrome.
We have begun to appreciate that the extent of this disorder is much wider than merely mental retardation. It is also a common cause of learning and emotional problems in mildly affected female carriers with normal IQs. These children present an enormous challenge to all child-care providers, be they in medicine, education, or in various therapy disciplines. Early identification is essential, a...
