Function

This gene encodes a vesicular glutamate transporter. The encoded protein transports the neurotransmitter glutamate into synaptic vesicles before it is released into the synaptic cleft.^[5]

Clinical significance

Mutations in this gene are the cause of autosomal-dominant nonsyndromic deafness type 25 (DFNA25).^[6][7]
