The Pathophysiology of Fragile X (and What It Teaches Us about Synapses)
Open accessAbstract
Fragile X is the most common known inherited cause of intellectual disability and autism, and it typically results from transcriptional silencing of FMR1 and loss of the encoded protein, FMRP (fragile X mental retardation protein). FMRP is an mRNA-binding protein that functions at many synapses to inhibit local translation stimulated by metabotropic glutamate receptors (mGluRs) 1 and 5. Recent studies on the biology of FMRP and the signaling pathways downstream of mGluR1/5 have yielded deeper insight into how synaptic protein synthesis and plasticity are regulated by experience. This new knowledge has also suggested ways that altered signaling and synaptic function can be corrected in fragile X, and human clinical trials based on this information are under way.

In the citing paper
“FMRP has recently been reported to modulate the rate of translational elongation of mRNAs that encode synaptic proteins33, suggesting that the decrease in FMRP expression that occurs in Fragile X syndrome may result in the dysregulation of synaptic protein expression owing to an impairment in translational control23.”
From Activity-dependent neuronal signalling and autism spectrum disorder (2013) · cites this paper as [23]
In the citing paper
“Fragile X syndrome results from a trinucleotide expansion (CGG) in FMR1, which encodes fragile X mental retardation protein (FMRP).”
From Activity-dependent neuronal signalling and autism spectrum disorder (2013) · cites this paper as [23]
In the citing paper
“The CGG expansion occurs within the 5′ untranslated region of the FMRP mRNA, resulting in decreased translation of the FMRP mRNA and a decrease in the amount of FMRP expressed in neurons.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
