Partington syndrome

Prevalence
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance

Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease

Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype

X-linked
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.

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]

Symptoms

The signs and symptoms of Partington syndrome vary but may include:[1][2]

  • Mild to moderate intellectual disability
  • Behavioral issues
  • Dystonia, especially affecting the movement of the hands
  • Dysarthria
  • Abnormal gait (style of walking)
  • Recurrent seizures

Partington syndrome usually occurs in males; when it occurs in females, the signs and symptoms are often less severe.[1]

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

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]

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

    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.

    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.
