FMRP, the protein missing in fragile X syndrome, is needed for the birth of new neurons, for regulating the translation of RNA into protein, and for maintaining the structural integrity of spiny neuronal projections, according to several new studies.

Charting the structure and function of the brain’s many circuits may unravel autism’s mysteries.
Children who have autism and their healthy siblings share patterns of brain activity that are different than those seen in children with no family history of the disorder, according to unpublished research presented at the IMFAR 2010 conference in Philadelphia.
Brain imaging reveals distinct signatures in the language circuits of young toddlers with autism while they sleep, according to unpublished data presented yesterday at the IMFAR 2010 meeting in Philadelphia.
Children with Williams syndrome — a rare genetic disorder that leads to mental retardation and overt friendliness — hold stereotypes based on gender, but not race, according to a report published in Current Biology. Because those with Williams syndrome don’t have social fear, the study suggests racial stereotypes are based partly on fear.
Variations in two genes needed to form connections between brain cells may be associated with autism spectrum disorder, according to a study published 25 March in Molecular Autism. Some variants in the genes seem to increase susceptibility to autism, whereas others protect children from developing the disorder.
