Zaspopathy, also called ZASP-related myofibril myopathy, is a novel autosomal dominant form of progressive muscular dystrophy, first described in 2005.
The disease encompasses multiple forms of both distal and proximal myopathies, and is caused by mutations in the gene referred to as ZASP.
The ZASP gene is located at chromosome 10, and encodes also-called Z-disk-associated protein.
Mutation in this protein causes disintergration of the Z-disk of contractile elements (myofibrils) in muscle cells.
Mutations of several other Z-disk related proteins, such as desmin, alfa-B-crystallin and myotilin can cause disorders similar to zaspopathy.
