Research indicates 42 genetic variations that are tied to dyslexia.
In the largest genome-wide association study on dyslexia, researchers from the University of Edinburgh in Scotland found 42 genetic variants correlated with dyslexia. The researchers analyzed data from 51,800 adults, all with self-reported dyslexia. The participants were involved with 23andMe, a DNA testing service. While the gene variations found linked to dyslexia do not necessarily cause the language-processing disorder, they might make it more likely to arise if combined with certain environmental factors.
Understanding genes associated with dyslexia can help to expand diagnostic tools as well as identify those who are more prone to this disorder. This is important in diagnosing and treating dyslexia at an early age to help mitigate future learning challenges.
