How genes, brain characteristics and intelligence are connected

Intelligence is partly heritable. There are studies that show that certain genetic variations are linked to better performance in intelligence tests. Other studies show that a variety of brain characteristics, such as network ...

A genetic map for complex diseases

Although heavily studied, the specific genetic causes of "complex diseases," a category of disorders which includes autism, diabetes and heart disease, are largely unknown due to byzantine genetic and environmental interactions.

Colonic gene mapping gives insights into intestinal diseases

Using a technique called spatial transcriptomics, researchers at Karolinska Institutet have analyzed the gene expression in the mouse colon and created a map showing where in the tissue individual genes are expressed. When ...

Whole-exome sequencing identifies inherited mutations in autism

While autism clearly runs in some families, few inherited genetic causes have been found. A major reason is that these causes are so varied that it's hard to find enough people with a given mutation to establish a clear pattern. ...

Genetics

New form of intellectual disability discovered

Researchers at the Centre for Addiction and Mental Health (CAMH) led a study discovering a gene for a new form of intellectual disability, as well as how it likely affects cognitive development by disrupting neuron functioning.
