Research sheds lights on cause of some chromosome disorders such as Down syndrome

Scientists have a better understanding of what causes an abnormal number of chromosomes in offspring, a condition called aneuploidy that encompasses the most common genetic disorders in humans, such as Down syndrome, and is a leading cause of pregnancy loss.

...... The research sheds light on the genetic underpinnings of aneuploidy, a condition marked by having an abnormal number of chromosomes. It is the underlying cause of many genetic diseases – such as Down syndrome, Edwards syndrome, and Patau syndrome – as well as many cases of pregnancy loss.
