A new method scans gene expression in live cells and could help scientists study autism genes.

Researchers have identified a distinctive pattern of gene expression in the white blood cells of young autistic boys.

Mutations in the gene CSDE1 lead to a constellation of developmental delays and conditions, including autism, according to a new study.

Mice lacking one copy of a gene called DDX3X have developmental delay and sensory, motor and behavioral problems — similar to those seen in people with a mutation in the gene.

Some traits of fragile X syndrome may be due to problems with mitochondria, the cell’s energy factories.

Researchers have developed a method for sequencing the genome of an intact single cell, revealing its spatial arrangement within the nucleus.

Researchers have used a new gene-editing technique to delete a segment of DNA associated with autism and schizophrenia from mouse brain cells.

Turning down the expression of a gene linked to autism leaves zebra finches singing disorganized songs.

Researchers have used the gene-editing tool CRISPR to disable the MECP2 gene in marmoset embryos. The six such marmosets created seem to recapitulate aspects of Rett syndrome.

Rats missing UBE3A, the gene mutated in people with Angelman syndrome, squeak frequently but tend not to be responsive to the play and squeaks of other rats.
