The clinical genome-wide DNA methylation test can diagnose genetic diseases that are missed by exome or genome sequencing and evaluate variants of unknown significance.

In PLOS this week: computational strategy for improving gene set analysis testing, miRNAs linked to sleep apnea, and more.

Researchers found 253 candidate disease genes, based on 10,927 exomes from patients with autism spectrum disorder, developmental delay, or intellectual disability.

In the long run, genome-wide DNA methylation profiling could be useful in diagnosing constitutional disorders as well as cancer.

The partners are planning to conduct meta-analyses of shared exome datasets from patients with inherited neurological disorders.

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.
