In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

Genetic testing can help doctors diagnose some neurological disorders, such as Huntington’s disease. It can also provide insights into a person’s risk of future health conditions. Genetic testing ...

"Monogenic" diseases, triggered by mutations in just one gene, may actually be more complex than scientists thought.

The genetic roots of a disease or disorder do not always grow into clear-cut, easily diagnosed clinical features. Even if a parent and child have the same genetic marker implicated in an outcome, such ...

Researchers have found that motor delay and low muscle tone were common signs of an underlying genetic diagnosis in children with neurodevelopment disorders. In a new study, UCLA Health researchers ...

Researchers have uncovered shared genetic pathways that link multiple psychiatric disorders. These new findings have the potential to change the way psychiatric disorders are diagnosed and treated, ...

Forbes contributors publish independent expert analyses and insights. Recent breakthroughs in genetics research may have uncovered new genes underlying common psychiatric disorders. Schizophrenia and ...

Genetic variants can take many different forms. For example, a single letter of the DNA alphabet might be miscopied, like a typo; or whole words, sentences or even chapters can be deleted or inserted ...

Severe mental disorders like major depressive disorder, bipolar disorder, and schizophrenia share a genetic overlap with ...

An international collective of researchers is delivering new insights into why having multiple psychiatric disorders is the norm rather than the exception. In a study published today in the journal ...
