A gene therapy administered after birth reverses disruptions in brain development observed in mice missing the FOXG1 gene. Spectrum previously reported on researchers whose work focuses on their own children’s conditions, as Soo-Kyung Lee has done with FOXG1 syndrome. The Scientist
“Our findings highlight that patterns of age-related changes in the brain may be influenced by demographic and phenotypic characteristics, and thus future studies should consider these when examining or controlling for age effects in analyses.” Human Brain Mapping
Zebrafish with autism-linked genetic variants show both altered auditory responses—hypersensitivity and delayed habituation—and brain-wide neuronal activity changes, according to a preprint. bioRxiv

Mice missing the autism-linked gene SCN2A in their oligodendrocytes show altered myelination and, in turn, changes in neuronal excitability and synaptic plasticity, according to a preprint. Spectrum has reported on the role of oligodendrocytes in autism. Research Square
Infants with two or more of a suite of behavioral differences are more likely to have autism or other developmental conditions at age 3 than are those without these differences. Autism
A machine-learning algorithm trained on videos of autistic children’s stereotyped movements can objectively recognize the presence and degree of such motor behaviors. JAMA Network Open
