Mice without DDX3X are slow to grow neurons

The gene helps neurons exit the cell-maturation cycle during fetal brain development, a new study shows. But male and female mice respond differently to DDX3X loss.

Precocious neurons may stunt brain growth in rare form of autism

The first animal model of MYT1L syndrome suggests that fast-maturing neurons lead to the unusually small brains, social deficits and other traits seen in people with the condition.

Jump-starting growth signaling reverses microcephaly in autism mouse model

A genetic therapy and an existing drug both restore typical brain size in mice missing DYRK1A, a top autism candidate gene, in the cerebral cortex, a new study shows. The animals typically have smaller brains than controls.
