An analysis of rare genetic variants identifies three genes—MAP1A, ANO8 and ANK2—that have a role in attention deficit hyperactivity disorder (ADHD) and investigates the potential underlying biological mechanisms.

A study of several longitudinal birth cohorts and cross-sectional cohorts finds only moderate overlap in genetic variants between autism that is diagnosed earlier and that diagnosed later, so they may represent aetiologically different conditions.

The age at which a person is diagnosed with autism can be partly explained by genetic factors.

Those diagnosed as small children typically have distinct genetic profile from those diagnosed later, study finds Autism should not be viewed as a single condition with a unified underlying cause, according to scientists who found that those diagnosed early in childhood typically have a distinct genetic profile to those diagnosed later. The international study, based on genetic data from more than 45,000 autistic people in Europe and the US, showed that those diagnosed in early childhood, typically before six years old, were more likely to show behavioural difficulties from early childhood, including problems with social interaction, but remain stable.

Sent diagnosticerede har ofte andre psykiatriske lidelser sammen med autisme. En af årsagerne kan være, at de har en særlig genetik, viser ny forskning.

“Kennedy would be less hazardous if he decided to do cardiac surgery. Then he would kill people only one at a time,” writes former CDC Director William Foege.

Nature Reviews Genetics, Published online: 12 May 2025; doi:10.1038/s41576-025-00843-0Genomic advances have enhanced our understanding of schizophrenia, bipolar disorder and major depressive disorder, revealing genetic architectures and risk mechanisms through large-scale genome-wide association studies and sequencing, which could address limitations in current diagnostic frameworks and treatment strategies in the future.

Genetic mutations in the DDX3X gene are associated with a neurodevelopmental disorder primarily affecting females. Here authors show that Ddx3x mediates sexual dimorphisms during brain development at ...

A genome-wide association study of age at onset of walking in over 70,000 infants found 11 significant loci. Age at onset of walking showed SNP heritability of 24%, a reliable polygenic score and gene...
