Study:How dyslexia affects children

Scientists have for the first time pinpointed a large number of genes that are reliably associated with dyslexia.
Around a third of the 42 genetic variants identified have been previously linked to general cognitive ability and educational attainment.
The researchers say their findings, published in Nature Genetics journal, aid our understanding of the biology behind why some children struggle to read or spell.
Dyslexia is known to run in families partly because of genetic factors.
Lead researcher Michelle Luciano, of the University of Edinburgh’s School of Philosophy, Psychology and Language Sciences, says the study sheds light on many unanswered questions around dyslexia.
Luciano said they were able to predict how well children and adults from four other research studies can read and spell using the genetic information from the study, but not with the accuracy needed for diagnostic use.
