MONDAY, Oct. 24, 2022 (HealthDay News) — Some children struggle to read or spell because of a condition called dyslexia that is known to run in families.
Now, researchers report they have pinpointed a large number of genes responsible for the disorder.
“Our findings show that common genetic differences have very similar effects in boys and girls, and that there is a genetic link between dyslexia and ambidexterity,” said lead researcher Michelle Luciano, of the University of Edinburgh’s School of Philosophy, Psychology and Language Sciences, in Scotland.
“Our results also suggest that dyslexia is very closely genetically related to performance on reading and spelling tests, reinforcing the importance of standardized testing in identifying dyslexia,” Luciano said in a university news release.
To come to those conclusions, the researchers tested the association between millions of genetic variants and dyslexia status, finding 42
