CLCN3 encodes ClC-3, a voltage-gated chloride channel protein with critical intracellular localization in synaptic vesicles, endosomes, and lysosomes Citation needed. The gene is located on chromosome 4 (4q22.1) and is highly expressed in the brain, particularly in the [hippocampus](/brain-regions/hippocampus), [cortex](/brain-regions/cortex), and cerebellum Citation needed.

Overview
CLCN3 (Chloride Voltage-Gated Channel 3) is a gene located on chromosome 4q22.1. The encoded protein is a voltage-gated chloride channel involved in cellular ion homeostasis, acidification of intracellular compartments, and neuronal function. CLCN3 mutations are associated with neurodegenerative diseases and lysosomal storage disorders. [@marger2011]
