Cousin comparison parses genetic effects in autism
A new study using family designs in Denmark investigates whether maternal genetics directly or indirectly influence autism risk in children. By comparing cousins, researchers aim to distinguish between genetic inheritance and prenatal environmental factors like maternal health conditions.
Why it matters
Understanding the genetic versus environmental drivers of autism is crucial for improving diagnostic accuracy and maternal health guidance.
An examination of the cousins of autistic children in Denmark, described in a new preprint , sheds light on the direct and indirect effects that maternal genetics may have on autism likelihood.
