Investing in genetic research has the potential to greatly enhance educational policies and our understanding of parenting, benefiting all children, according to a recent paper led by the University of Surrey.
In a study published in Nature Genetics, scientists outline various evidence indicating that genetics play a role in influencing infant development. While rare genetic disorders receive significant attention, the researchers argue that common genetic differences in children, which make up their genetic makeup, could also aid in developing early interventions and improving our understanding of infancy for all children.
The researchers highlight that infancy, compared to later life stages, has been relatively under-researched despite the potential benefits of genetic research. While the importance of environmental factors in infant development is well-recognized, the research team conducted an analysis of published twin and molecular genetic studies. They found evidence suggesting that genes play a vital role in shaping children’s development during the first three years of life. However, further research is necessary to fully grasp the connection between DNA and individual differences in development.
Professor Angelica Ronald, a co-author of the paper from the School of Psychology at the University of Surrey, stated:
“Infancy is a critical period with significant advancements in motor, social, and language skills, among others. Our research indicates that genetics profoundly influence these early traits.
“By understanding and pinpointing genetic influences early on, we can make a meaningful impact on many children and their families. This understanding can enable parents, healthcare providers, and educators to offer better support for a child’s development and develop strategies to tackle potential challenges in the long run.”
The researchers aim to encourage funders, policymakers, and fellow scientists to invest in studies focusing on the infancy stage. They argue that the potential impact on the population is substantial, as infants have their whole lives ahead of them.
Dr. Anna Gui, another co-author of the paper and a Lecturer at the University of Essex, commented:
“Our findings present compelling evidence from twin studies, adoption research, polygenic scores, and analysis of infant characteristics that genetics significantly impact early development.
“Polygenic scores, which aggregate the effects of numerous genetic variations, illustrate how genetic influences affect crucial milestones like walking and talking. This knowledge can greatly benefit children’s lives.
“With this insight, we aspire to design improved early education programs and interventions to aid parents and professionals in supporting children’s development more effectively.”
