  • The relationship between camouflaging behavior and mental health problems among autistic people is culturally dependent, according to an international study: linear in the United Kingdom and U-shaped in Japan. Molecular Autism
  • Mice engineered to overexpress the EIF4E protein, which facilitates protein synthesis, have altered striatal dopamine neurotransmission and behavioral inflexibility, according to a preprint. Spectrum has previously covered other findings in this mouse model. bioRxiv
  • Infants with autistic siblings and who are later diagnosed with autism themselves have altered white-matter development in the arcuate fasciculus, a neuronal tract connecting brain areas related to language. Molecular Psychiatry
  • Dysfunction in the autism-linked gene SCN2A interferes with an eye reflex in children and in mice. Spectrum previously reported on the preprint version of this study. Neuron
A slice of a cerebellum.
Reflex reversal: Counteracting the effects of an SCN2A mutation in the mouse cerebellum helps restore the eye reflex in adolescent mice.
  • Half of children evaluated for autism in the United States use federally funded early-intervention services, and Black children are less likely to access services than white children. Autism
  • A novel RNA-editing technique, with high activity and minimal off-target effects, appears to remedy gene variants linked to conditions such as Rett syndrome and autism, according to a preprint. bioRxiv
  • Rats missing the FMR1 gene show altered glutamate and GABA neurotransmission, as well as hyperactivity and cognitive deficits. Translational Psychiatry
