Fragile X Syndrome (FXS) occurs as a result of a silenced fragile X mental retardation 1 gene (<i>FMR1</i>) and subsequent loss of fragile X mental retardation protein (FMRP) expression.

In the absence of FMRP, these same mRNAs may be partially translated via alternative mRNPs, although perhaps abnormally localized or regulated, resulting in typical fragile X syndrome.

We further suggest that the failure of FMRP to oligomerize, caused by the I304N mutation, may contribute to the pathophysiological events leading to fragile X syndrome.

Fragile X syndrome is caused by the absence of the mRNA-binding protein Fragile X mental retardation protein (FMRP), which may play a role in activity-regulated localization and translation of mRNA in dendrites and at synapses.

This study suggests that intragenic FMR1 variants, although much less frequent than CGG expansions, are a significant mutational mechanism leading to FXS and demonstrates the interest of HTS approaches to detect them in ID patients with a negative standard work-up.
