Research links variations in the gene GRIN2A to a higher risk of developing schizophrenia and other forms of mental illness.

Scientists have discovered that a single gene, GRIN2A, can directly cause mental illness—something previously thought to stem only from many genes acting together. People with certain variants of this gene often develop psychiatric symptoms much earlier than expected,

While some genes have been linked to specific disorders, it may not always be clear how changes in those genes can lead to disease. There have been many genes linked to autism spectrum disorder (ASD), for example, but their contribution to the disorder ...

CDKL5, one of the five members of the CDKL family of genes, is important for proper neurodevelopment and associated with seizures. However, the role the other four members of this family play in health and disease is unknown. In addition, the researchers ...

No single gene causes OCD, but identifying the genetic markers linked to the condition can help clarify how it develops. Viktoria Ruban/iStock via Getty Images Plus Obsessive compulsive disorder has many unknowns, including what causes it, why symptoms can ...

Scientists have been trying to identify the exact causes of Alzheimer's disease for many years, and while we know that pathologies like tau tangles and amyloid plaques are related to the neurodegenerative disorder, there is still much that is unknown.

A new genetic study of more than 50,000 obsessive-compulsive disorder (OCD) cases has linked around 250 genes to the condition, including more than two dozen identified as likely causal, in about 30 regions of the human genome. The study describes ...

Research on Tourette’s indicates that the condition is strongly influenced by inherited genetic factors, with environmental factors also contributing to its development. Tourette syndrome is a neurodevelopmental disorder that causes repetitive ...
