A team of researchers based at Yale University School of Medicine, the University of Houston (United States of America), the University of Toronto and Brock University (Canada) have explored why some children experience reading and comprehension difficulties over others by using a multi disciplinary approach in the article "A molecular-genetic and imaging-genetic approach to specific comprehension difficulties in children”.
Following DNA sequencing of genetic samples from 1432 American children aged from 8 to 15 years old, representing African and Hispanic descent, the results revealed a specific allele is associated with reading and language comprehension problems. Magnetic resonance imaging of 58 randomly selected children provided supporting evidence these genes affect brain networks and their functional connectivity.
The researchers report the study will help identify children experiencing reading and comprehension problems so parents can ameliorate the problem at an earlier age to minimise learning delays later on in life.
