Presentation
The article by McManus et al1 also expands our knowledge on phenotypic presentations of Perry syndrome. Recurrent syncopes have not been previously associated with this condition. [nzma.org.nz]
Weight should be monitored and a high caloric diet should be implemented when weight loss is present. With worsening symptoms hospitalization and major medical assistance is often required. [orpha.net]
The cardinal signs of Perry syndrome were present in all three probands with symptomatic disease onset in their sixth decade of life. Parkinsonian signs were mild to moderate with a poor response to dopaminergic treatment. [neurology.org]
In the seven families reported previously and the two new families presented herein (the Hawaii family and the Fukuoka-4 Japanese family), the mean disease onset age is 48 years (range: 35-61) and the mean disease duration five years (range: 2-10). [ncbi.nlm.nih.gov]
Entire Body System
- Weight Loss
The early signs include parkinsonism, depression and weight loss, whereas hypoventilation is a late feature. [ncbi.nlm.nih.gov]
Weight should be monitored and a high caloric diet should be implemented when weight loss is present. With worsening symptoms hospitalization and major medical assistance is often required. [rarediseases.info.nih.gov]
Many affected individuals also experience significant, unexplained weight loss early in the disease. Hypoventilation is a later feature of Perry syndrome. [medlineplus.gov]
- Wheelchair Bound
Patients are often bedridden or wheelchair bound as motor impairment may be severe at a later stage of the disease. [orpha.net]
Respiratoric
- Respiratory Insufficiency
A diaphragmatic pacemaker was implanted in the proband from the Colombian family to treat her respiratory insufficiency. Dopaminergic therapy was initiated in probands from two families. [ncbi.nlm.nih.gov]
All affected family relatives including the probands from the New Zealand and US families died of respiratory insufficiency. [neurology.org]
Musculoskeletal
- Short Arm
This process is due to mutations in the gene DCTN1 (dynactin subunit 1), located on the short arm of chromosome 2 (2p13). This gene encodes dynactin-1 protein. P150 and P135: cells in at least two different versions of this protein are produced. [ivami.com]

Treatment
Diaphragmatic pacemakers should be considered as an effective symptomatic treatment option. [ncbi.nlm.nih.gov]

Management and treatment There is no cure for Perry syndrome. Symptomatic treatment requires a multidisciplinary team. Dopaminergic therapy is given to patients to help with parkinsonism, usually using levodopa / carbidopa. [orpha.net]
Prognosis
Prognosis Perry syndrome progresses rapidly and the prognosis is poor. Death is due to respiratory insufficiency or suicide or, in some cases, can be sudden and unexplained. [orpha.net]
Treatment and prognosis Management of Perry syndrome is symptomatic, such as trialing levodopa therapy for parkinsonism, and managing respiratory symptoms with non-invasive ventilation or diaphragmatic pacemaker insertion 2,7. [radiopaedia.org]
What is the prognosis for Parry-Romberg syndrome? The prognosis for individuals with Parry-Romberg syndrome varies. In some cases, the atrophy ends before the entire face is affected. [medicinenet.com]
Etiology
Etiology Perry syndrome is caused by mutations (five identified to date) in exon 2 of the dynactin DCTN1 gene coding for p150glued, the major subunit of the dynactin protein complex. [orpha.net]

Epidemiology
“Previous studies had suggested that weight loss has only partial benefits for women with PCOS,” said Dr Ken Ong, of the MRC Epidemiology Unit and study co-lead. [cam.ac.uk]
Summary Epidemiology The prevalence is unknown. It has been described in 53 cases from 11 families to date in Canada, U.S., U.K., France, Turkey and Japan. [orpha.net]

Prevention
Early diagnosis prevents life-threatening acute respiratory failure. Diaphragmatic pacemakers should be considered as an effective symptomatic treatment option. [ncbi.nlm.nih.gov]
In severe cases, surgery is needed to prevent a blockage in the upper airway. Some children need surgery to make a hole in their airway or to move their jaw forward. [medlineplus.gov]
Dry eyes can be a chronic condition, but your eye doctor can prescribe treatment to keep your eyes healthy, more comfortable, and prevent your vision from being affected. [hasletteyecare.com]
Early diagnosis may prevent life-threatening acute respiratory failure. Diaphragmatic pacemakers should be considered as a safe and effective symptomatic treatment option. Parkinsonian features, although always present, may not be disabling. [neurology.org]
