[[http://www.uniprot.org/uniprot/DAG1_HUMAN DAG1_HUMAN]] Defects in DAG1 are the cause of muscular dystrophy-dystroglycanopathy limb-girdle type C7 (MDDGC7) [MIM:[http://omim.org/entry/613818 613818]]. An autosomal recessive muscular dystrophy showing onset in early childhood, and associated with mental retardation without structural brain anomalies. Note=MDDGC7 is caused by DAG1 mutations that interfere with normal post-translational processing, resulting in defective DAG1 glycosylation and impaired interactions with extracellular-matrix components. Other muscular dystrophy-dystroglycanopathies are caused by defects in enzymes involved in protein O-glycosylation.<ref>PMID:21388311</ref>

[[http://www.uniprot.org/uniprot/DAG1_HUMAN DAG1_HUMAN]] The dystroglycan complex is involved in a number of processes including laminin and basement membrane assembly, sarcolemmal stability, cell survival, peripheral nerve myelination, nodal structure, cell migration, and epithelial polarization.<ref>PMID:9851927</ref> <ref>PMID:11724572</ref> <ref>PMID:16254364</ref> <ref>PMID:17360738</ref> Alpha-dystroglycan is an extracellular peripheral glycoprotein that acts as a receptor for both extracellular matrix proteins containing laminin-G domains, and for certain adenoviruses.
