Orpha Number: 1873

Definition
Jalili syndrome is characterized by the association of amelogenesis imperfecta (AI; see this term) and cone-rod retinal dystrophy (CORD; see this term).

Epidemiology
It has been described in only one family with 29 affected individuals.

Clinical description
AI is a generic term for an inherited group of dental diseases in which the common clinical feature is an abnormality of tooth enamel. The enamel may be thin but normal, and/or hypomineralized. CORD is a rare retinal disorder that leads to an initial loss of central vision, color vision and photophobia before the age of 10 years with subsequent night blindness and visual field restriction.

Etiology
Mutations in the CNNM4 gene (2q11.2), which is implicated in metal ion transport, have been identified in several families.

Genetic counseling
Jalili syndrome is transmitted in an autosomal recessive manner.

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.

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.

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.
