Dyslexia and ADHD Share Genetic Links, Study Shows
The article from Medical Xpress titled “Dyslexia and ADHD share genetic links, study shows” discusses a recent study that has shed new light on the genetic basis of dyslexia, particularly in relation to attention deficit hyperactivity disorder (ADHD) and other neurodevelopmental and psychiatric traits. Here is a summary of the key points:

Study Overview
The study, led by the University of Edinburgh, is the first to explore the genetic links to dyslexia in the context of neurodevelopmental and psychiatric traits. It analyzed large public anonymized datasets of genetic data on 10 neurodevelopmental and psychiatric conditions, including ADHD, from the Psychiatric Genomics Consortium and additional data from 23andMe.
Findings
The researchers identified five genetically linked clusters known as latent genomic factors among the 10 psychiatric traits studied. ADHD was more strongly related to an attention and learning difficulties factor than to factors related to neurodevelopmental traits like autism and Tourette syndrome.
Detailed analyses revealed 49 genetic regions and 174 genes shared between dyslexia and ADHD, with 40 regions and 121 genes not previously identified.
Implications
The findings could help in tailoring targeted educational, employment, and well-being support systems for individuals with dyslexia or ADHD. The study highlights the importance of understanding the genetic overlap between dyslexia and ADHD to improve diagnostic and therapeutic approaches.
Future Research Directions
The researchers suggest that future studies should include other learning difficulties such as dyscalculia or dyspraxia to gain a more nuanced understanding of the relationships between these conditions.
Publication Details
The study was published in the journal Molecular Psychiatry and is available under the DOI 10.1038/s41380-024-02649-8.
This study provides significant insights into the genetic underpinnings of dyslexia and its overlap with ADHD, which could lead to more effective interventions for individuals affected by these conditions.
