Modelling brain dopamine-serotonin vesicular transport disease in Caenorhabditis elegans.

ABSTRACT: Brain dopamine-serotonin vesicular transport disease is a rare disease caused by autosomal recessive mutations in the SLC18A2 gene, which encodes the VMAT2 protein. VMAT2 is a membrane protein responsible for vesicular transport of monoamines, and its disruption negatively affects neurotransmission. This results in a severe neurodevelopmental disorder affecting motor skills and development, and causes muscular hypotonia. The condition was initially described in a consanguineous Saudi Arabian family with affected siblings homozygous for a P387L mutation. We subsequently found a second mutation in a New Zealand family (homozygous P237H), which was later also identified in an Iraqi family. Pramipexole has been shown to have some therapeutic benefit.
