Genes

A collection of rare genetic variants associated with autism and schizophrenia also seem to increase a person’s odds of having attention deficit hyperactivity disorder.

Autistic people who carry mutations in a gene called PTEN have distinct behavioral and motor problems.

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.

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

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.

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

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.

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