intellectual disability

Mutations in the WDR26 gene appear to contribute to a condition marked by intellectual disability, facial dysmorphism, and movement problems.

Two studies described de novo gene mutations involved in autism spectrum disorder and other neurodevelopmental conditions, while weeding out unrelated changes.

By focusing on sequences that have diverged rapidly in humans, researchers identified regulatory sequences suspected of affecting neural processes.

Exome sequences from thousands of parent-child trios led to 10 new genes in which de novo mutations are over-represented in individuals with intellectual disability. 

In a cohort of some 300 people with intellectual disability, a genomic approach offered a likely diagnosis some 60 percent of the time.

Researchers diagnosed almost 70 percent of the neurometabolic cases they tackled, using exome sequence data for dozens of affected children and their families.

Using whole-exome sequencing early in the diagnostic process could save $3,500 on average in patients who obtain a diagnosis from it and $1,700 in patients who do not.

An international team tracked down de novo mutations in the CHAMP1 gene in five children with intellectual and motor delays, speech impairment, and other symptoms.

Researchers at the Manchester Centre for Genomic Medicine are using the platform to identify genetic alterations tied to cancer and developmental disorders and disabilities.

More than 10 percent of individuals in an unselected population carried recurrent syndrome-associated CNVs or rare autosomal CNVs with potential ties to cognitive ability.
