Researchers believe they have identified the gene responsible for dyslexia, a condition that makes reading and writing difficult for millions of people.
Scientists from the Max Planck Institute for Psycholinguistics, Australia’s QIMR Berghofer Medical Research Institute, the US company 23andMe Inc, and the University of Edinburgh have conducted what is believed to be the largest genetic study of dyslexia to date. The results were recently published in Nature. genetics.
The study found 42 significant genes while analyzing the relationship between millions of genetic variants and dyslexia. Researchers had access to data on her 50,000 adults who suffer from dyslexia and about 1 million adults who do not have the disease.
Some genes are major contributors to language delays and other critical thinking abilities, which can negatively affect an individual’s academic performance. More than 30% of his genetic alterations discovered by scientists traced back to these cognitive deficits, many of which were related to functions essential for skill learning and development.

“Our findings show that common genetic differences have very similar effects on boys and girls, indicating a genetic link between dyslexia and ambidextrousity,” said the study. Michel Luciano of the University of Edinburgh, lead author of Philosophy, Psychology, Linguistic Sciences.
“Our results also suggest that dyslexia is genetically very closely related to reading and writing test performance, reinforcing the importance of standardized tests in identifying dyslexia. I do,” Luciano added.

According to this study, genes associated with dyslexia also appear to affect individuals diagnosed with attention deficit hyperactivity disorder.
Chinese-speaking participants were also affected by genetic variation, indicating that the reading and writing processes are not segregated into one language.
