Abstract

In addition to muscle disease, defects in processing and assembly of the dystrophin-glycoprotein complex (DGC) are associated with a spectrum of brain abnormalities ranging from mild cognitive impairment (MCI) to neuronal migration disorders. In brain, the DGC is involved in the organisation of GABA(A) receptors (GABA(A)Rs) and aquaporin-4 (AQP4)-containing protein complexes in neurons and glia, respectively. During development, defects in the glycosylation of α-dystroglycan that impair its ability to interact with the extracellular matrix (ECM) are frequently associated with cobblestone lissencephaly and mental retardation. Furthermore, mutations in the gene encoding ɛ-sarcoglycan (SGCE) cause the neurogenic movement disorder myoclonus dystonia syndrome. In this review, we describe recent progress in defining distinct roles for the DGC in neurons and glia.
