Of the DEPs identified in the study, the Snap25 protein is of particular interest given its important function in the SNARE protein complex by maintaining the complex’s assembly and stability and proper synaptic transmission and brain function, if impaired, can lead to impaired neurotransmitter release (including dopamine) and eventually inducing neuropsychiatric disorders [30], such as ADHD. Here, SNAP25 is linked to attention deficit-hyperactivity disorder.
