Bowen-Conradi syndrome

Title

Other Names:

Bowen Hutterite syndrome (formerly); Bowen-Conradi Hutterite syndrome; BWCNS

Categories:

Congenital and Genetic Diseases; Nervous System Diseases

Summary Summary

Bowen-Conradi syndrome is a very rare genetic disorder characterized by growth delays before birth, failure to thrive during infancy, and malformations of the head and facial area. Other physical abnormalities include small head, prominent nose, small chin, mild joint restriction, clinodactyly, camptodactyly, foot deformities, and/or undescended testes (cryptorchidism) in affected males. Some affected infants may also have kidney, brain, and/or other abnormalities. Many infants die within the first few months of life. This condition is inherited in an autosomal recessive fashion.^[1]^[2]

Symptoms Symptoms

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.

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.

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.
