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]

The Human Phenotype Ontology (HPO) provides the following list of features that have been reported in people with this condition. Much of the information in the HPO comes from Orphanet, a European rare disease database. If available, the list includes a rough estimate of how common a feature is (its frequency). Frequencies are based on a specific study and may not be representative of all studies. You can use the MedlinePlus Medical Dictionary for definitions of the terms below.

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.
