CHAT

A gene on chromosome 10q11.2 that encodes choline acetyltransferase, which binds acetylCoA to choline, controlling acetylcholine production at the synapses of the autonomic nervous system, muscle and the sympathetic nervous system.

Molecular pathology
Polymorphisms of CHAT have been associated with choline acetyltransferase depletion in Alzheimer’s disease and cognitive impairment; CHAT mutations are associated with congenital myasthenic syndrome associated with episodic apnoea.

comparative advantages of using computer-mediated communication and face-to-face communication
According to Markey (2000), interaction via Computer-Mediated Communication (CMC) is governed by the same social laws as in other contexts of communication but the main drawback to Computer-Mediated Communication Systems is the scarcity and the poor level of social information transmitted by such systems.
