Dyslexia is a learning disorder that involves difficulty reading due to problems decoding words and identifying speech sounds. Symptoms of dyslexia include; late talking, learning new words slowly, reading below the expected level for their grade, and more. There is no cure for dyslexia however parental support and tutoring at school can help the child to read better. Science has been studying what genes drive dyslexia. Researchers have begun to pinpoint specific genes responsible for the disorder. The findings show that common genetic differences have the same effect on both genders. Also, there is a linkage between dyslexia and ambidexterity. The results also showed that dyslexia is very closely genetically related to performance on reading and spelling tests. To determine these conclusions, the researchers tested millions of genes and genetic variants and found 42 significant variants. Many of the genetic variants that were linked to dyslexia were also linked to attention deficit hyperactivity disorder (ADHD). The study also found that several genetic variants were associated with the same symptoms of dyslexia in different languages, such as Chinese. This was the largest genetic study on dyslexia and is a great start at determining the specific genetic markers for the learning disorder.
