  • Improvements in in-vivo Perturb-seq, a method that uses CRISPR and single-cell transcriptomics, enable more rapid and efficient targeting of cells throughout the developing brain. Use of the technique revealed that loss of function of the autism-linked FOXG1 gene has cell- and layer-specific effects in mouse cortex. Cell
  • A new study challenges the idea that the MECP2 gene, which is linked to autism and Rett syndrome, forms condensates—molecular compartments that act like drops of oil in water—with heterochromatin. In 2020, Spectrum reported on the evidence and uncertainties surrounding these interactions, which could have implications for how MECP2 function is disrupted in Rett syndrome. Nature Communications
  • Inconsistencies in age-related changes in brain structure and function have been found in two cohorts of neurodivergent children and adolescents, according to a preprint. bioRxiv

Sex differences: Rates of cortical thinning during development are increased in autistic children (red/orange/yellow), with different patterns in girls (left two) and boys (right two).
  • Wearable sensors can detect early movement characteristics that have some predictive value for an eventual autism diagnosis. Autism Research
  • Children with tuberous sclerosis complex and autism are more likely to have altered white-matter development than are their peers without autism. Journal of Child Neurology
  • The trajectory of cortical thickness in autistic girls differs from that of autistic boys. Molecular Psychiatry
