Michelle Luciano and her team at the University of Edinburgh sought to find more concrete genetic causes for dyslexia. They conducted a study that compared the genomes of over a million people to see if there were noticeable difference between those with dyslexia and those without. They were able to find 42 variants that were significantly found much more in those with dyslexia. There did not appear to be any difference in these variants between sexes, ages, or ethnicity. These traits seem to only have small effects when acting alone which is common for polygenic traits - implying that the genetic basis of dyslexia is very complex.
I think this research is both fascinating and important. Learning more about the genetic causes for intellectual disorders could ultimately help mend the academic gap that many students find themselves in. Often times the school does not have the resources or training to properly accommodate students with learning disabilities. As a result there academic progress slows down or get put on hold and the older a student gets, the harder it is to catch back up. However, if we are able to prescreen embryos and babies for things like dyslexia, we could immediately implement the techniques need to limit the effect on their reading and writing. Focusing on it from a young age will make them more likely for success in secondary and higher education.
