Frequency
Perry syndrome is very rare; about 50 affected individuals have been reported worldwide.
Causes
Perry syndrome results from mutations in the DCTN1 gene. This gene provides instructions for making a protein called dynactin-1, which is involved in the transport of materials within cells. To move materials, dynactin-1 interacts with other proteins and with a track-like system of small tubes called microtubules. These components work together like a conveyer belt to move materials within cells. This transport system appears to be particularly important for the normal function and survival of nerve cells (neurons) in the brain.
Mutations in the DCTN1 gene alter the structure of dynactin-1, making it less able to attach (bind) to microtubules and transport materials within cells. This abnormality causes neurons to malfunction and ultimately die. A gradual loss of neurons in areas of the brain that regulate movement, emotion, and breathing underlies the signs and symptoms of Perry syndrome.
Inheritance
This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder.
In most cases, an affected person inherits the mutation from one affected parent. However, some cases result from new mutations in the gene and occur in people with no history of the disorder in their family.
