Definition
BNAR syndrome is a very rare multiple congenital anomaly syndrome characterized by a bifid nose (see this term) (with bulbous nasal tip but not associated with hypertelorism) with or without the presence of anal defects (i.e. anteriorly placed anus, rectal stenosis or atresia) and renal dysplasia (unilateral or bilateral renal agenesis, see these terms) and without intellectual disability. BNAR syndrome is phenotypically related to Fraser syndrome and oculotrichoanal syndrome (see these terms).

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.

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.
