Zaspopathy,[1] also called ZASP-related myofibril myopathy,[2] is a novel autosomal dominant[3] form of progressive muscular dystrophy, first described in 2005.
Cause[edit]
The disease encompasses multiple forms of both distal and proximal myopathies, and is caused by mutations in the gene referred to as ZASP.[3]
Pathophysiology[edit]
The ZASP gene is located at chromosome 10, and encodes also-called Z-disk-associated protein. Mutations in this protein causes disintegration of the Z-disk of contractile elements (myofibrils) in muscle cells.[citation needed]
Mutations of several other Z-disk related proteins, such as desmin, alfa-B-crystallin and myotilin can cause disorders similar to zaspopathy.[citation needed]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
