Prenatal pruning of neurons with copy number variants; and more

A study found that many prenatal cortical neurons carry copy number variants, but most are eliminated before or shortly after birth, with neurons having high variant counts showing altered synaptic gene expression and being targeted for removal. This pruning process may help prevent the development of dysfunctional neural connections.
