ABSTRACT16p11.2 deletion syndrome is a severe genetic disorder associated with the deletion of 27 genes from a Copy Number Variant region on human chromosome 16. Symptoms associated include cognitive impairment, language and motor delay, epilepsy or seizures, psychiatric disorders, autism spectrum disorder (ASD), changes in head size and body weight, and dysmorphic features, with a crucial need to define genes and mechanisms responsible for symptomatology.

Symptoms associated include cognitive impairment, language and motor delay, epilepsy or seizures, psychiatric disorders, autism spectrum disorder (ASD), changes in head size and body weight, and dysmorphic features, with a crucial need to define genes and mechanisms responsible for symptomatology. In this review, we analyze the clinical associations and biological pathways of 16p11.2 locus genes and identify that a majority of 16p11.2 genes relate to metabolic processes. We present a hypothesis in which changes in the dosage of 16p11.2 metabolic genes contribute to pathology through direct or indirect alterations in pathways that include amino acids or proteins, DNA, RNA, catabolism, lipid, energy (carbohydrate). This hypothesis suggests that research into the specific roles of each metabolic gene will help identify useful therapeutic targets.
