Researchers are using dogs as models of psychiatric and behavioral conditions, including obsessive-compulsive disorder and autism.

The Psychiatric GWAS Consortium has released its first batch of analyses, identifying several significant common variations associated with schizophrenia. The results were presented Sunday at the World Congress of Psychiatric Genetics in San Diego.

A team of British researchers has garnered some of the first genetic evidence supporting their theory that sex hormones play a role in the development of autism.

Several new genetic variants associated with schizophrenia lie in regions important for immune function and associated with autism. This suggests that both disorders stem partly from abnormal activation of the immune system, say some researchers.

Applying an emerging technique that combines genetic data and brain scans, researchers have identified two new genes involved in schizophrenia. The method, called ‘imaging genetics’, holds promise for linking genes to brain function in complex psychiatric disorders, including autism.

In the past few months, researchers have published dozens of reports linking single-nucleotide polymorphisms (SNPs) with susceptibility to a range of common diseases.

At first glance, the waiting room at the Ministry of Health Hospital in Muscat, Oman, may look different than that of your average American hospital. Men dressed all in white and women in black burqas wait in separate rooms, even if they are members of the same family. But talking to these families soon reveals just how similar they are to their American counterparts, says Christopher Walsh, a neurologist who has studied neurodevelopmental disorders in the Middle East for nearly 10 years.
