Abstract
Global developmental delay/intellectual disability (GDD/ID) is an enormous group of neurodevelopmental disorders with diverse clinical and genetic heterogeneity. The estimated prevalence of GDD/ID was 1%-3%, affecting about 150 million people. GDD/ID is one of the leading causes of disability in children worldwide. The causes of GDD/ID are complex, comprising genetic and environmental factors. It is often co-morbid with a variety of psychiatric behavioral disorders, such as autism spectrum disorder and attention deficit hyperactivity disorder. Owing to the improvement of genetic technology, monogenic GDD/ID has been one of the hot-spot research in genomic era, and the relevant preventive measures deserve extensive attention. In this review, we summarized the advances in genetics and prevention of monogenic GDD/ID.
