Summary Summary

Partington syndrome is a rare neurological condition that is primarily characterized by mild to moderate intellectual disability and dystonia of the hands. Other signs and symptoms may include dysarthria, behavioral abnormalities, recurrent seizures and/or an unusual gait (style of walking). Partington syndrome usually occurs in males; when it occurs in females, the signs and symptoms are often less severe. It is caused by changes (mutations) in the ARX gene and is inherited in an X-linked recessive manner. Treatment is based on the signs and symptoms present in each person.^[1]^[2]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cause Cause

Partington syndrome is caused by changes (mutations) in the ARX gene, which encodes a protein that regulates the activity of other genes. This protein is particularly important in the developing brain where it plays many roles (i.e. assisting with the movement and communication of neurons). Specific changes in the ARX gene impair the function of the protein, which may disrupt normal neuronal migration. This can lead to the many signs and symptoms associated with Partington syndrome.^[1]

Inheritance Inheritance

Partington syndrome is inherited in an X-linked recessive manner.^[1] A condition is considered X-linked if the mutated gene that causes the condition is located on the X chromosome, one of the two sex chromosomes (the Y chromosome is the other sex chromosome). Women have two X chromosomes and men have an X and a Y chromosome.

In X-linked recessive conditions, men develop the condition if they inherit one gene mutation (they have only one X chromosome). Females are generally only affected if they have two gene mutations (they have two X chromosomes), although some females may rarely have a mild form of the condition if they only inherit one mutation. A woman with an X-linked recessive condition will pass the mutation on to all of her sons and daughters. This means that all of her sons will have the condition and all of her daughters will be carriers. A man with an X-linked recessive condition will pass the mutation to all of his daughters (carriers) and none of his sons.

Diagnosis Diagnosis

Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.

Testing Resources

The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

Treatment Treatment

The treatment of Partington syndrome is based on the signs and symptoms present in each person. For example, dystonia of the hands and other parts of the body may be treated with a variety of therapies including medications and/or physical therapy.^[3] Speech therapy may be recommended for children with dysarthria. Medications may be prescribed to help prevent and/or control recurrent seizures. Children with mild to moderate intellectual disability may benefit from special education services.

For personalized information about the treatment and management of Partington syndrome, please speak to a healthcare provider.

Find a Specialist Find a Specialist

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. Online directories are provided by the American College of Medical Genetics and the National Society of Genetic Counselors. If you need additional help, contact a GARD Information Specialist. You can also learn more about genetic consultations from Genetics Home Reference.

Organizations Organizations

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
