Clinical Importance and Applications
Recent studies link mutations in genes encoding neurexin and neuroligin to a spectrum of cognitive disorders, such as autism spectrum disorders (ASDs), schizophrenia, and mental retardation. Cognitive diseases remain difficult to understand, as they are characterized by subtle changes in a subgroup of synapses in a circuit rather than impairment of all systems in all circuits. Depending on the circuit, these subtle synapse changes may produce different neurological symptoms, leading to classification of different diseases. Counterarguments to the relationship between cognitive disorders and these mutations exist, prompting further investigation into the underlying mechanisms producing these cognitive disorders.
