Fragile X syndrome: (What's) lost in translation?

Transcription, translation and fragile X syndrome.

The fragile X mental retardation protein (FMRP) plays a role in the control of local protein synthesis in the dendrites. Loss of its production in fragile X syndrome is associated with transcriptional dysregulation of the gene. Recent work demonstrates that Sp1 and NRF1 transcriptionally control this gene. Other studies reveal how the microRNA pathway and signaling are related to FMRP function ...

Fragile X Syndrome Therapeutics: Translation, Meet Translational Medicine

Fragile X syndrome, a common cause of intellectual disability and autism, is thought to occur due to abnormal regulation of neuronal protein synthesis. A study by Osterweil et al. (2013), in this issue, demonstrates that the HMG-CoA reductase inhibitor lovastatin can normalize protein synthesis and also reduce audiogenic seizures in Fmr1 knockout mice.

The 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...

Fragile X syndrome.

Fragile X syndrome

Fragile X syndrome occurs as a result of a mutation of the fragile X mental retardation 1 (FMR1) gene on the bottom of the X chromosome (Pic. 1), which encodes fragile X mental retardation protein (FMRP). This protein, most commonly found in the brain, is essential for normal cognitive development and female reproductive function. The CGG triplet that means gene segment consisting of a cytosine...
