• Oculocerebrocutaneous Syndrome

Disease at a Glance

Summary
Oculocerebrocutaneous (OCC) syndrome is a rare genetic disorder characterized primarily by eye, skin, and brain malformations. It has been described mostly in males. Findings in affected individuals may include orbital cysts, areas of underdeveloped (hypoplastic) or absent (aplastic) skin, and underdevelopment (hypoplasia) or absence (agenesis) of the band of nerve fibers that joins the brain's hemispheres (corpus callosum). Diagnosis is confirmed on the basis of specific MRI findings. In some affected individuals, the eye, skin, and brain findings involve only one side of the body. In these cases, the left side is involved twice as often as the right side. Additional findings may include rib and vertebral anomalies and craniofacial anomalies. Developmental delay and intellectual disability may be present and can vary from mild to profound. Approximately 50% of affected individuals have seizures. The exact cause of OCC syndrome is not known. In most cases, the affected individual is the first person in the family to have the disorder.

Next Steps

Talking with the Medical Team

Good communication between the patient, family, and medical team can lead to an accurate diagnosis. In addition, health care decisions can be made together which improves the patient’s well-being and quality of life.

Describing Symptoms

Describe details about the symptoms. Because there may be many different causes for a single symptom, it is best not to make a conclusion about the diagnosis. The detailed descriptions help the medical provider determine the correct diagnosis.

To help describe a symptom:

  • Use a smartphone or a notebook to record each symptom before the appointment
  • Describe each symptom by answering the following questions:
    • When did the symptom start?
    • How often does it happen?
    • Does anything make it better or worse?
  • Tell the medical team whether any symptoms affect daily activities

Preparing for the First Visit

Working with a medical team to find a diagnosis can be a long process that will require more than one appointment. Make better health decisions by being prepared for the first visit with each member of the medical team.

    Make informed decisions about health care: 
    • Prepare a list of questions and concerns before the appointment
    • List the most important questions first, not all questions may be answered in the first visit
    • Ask questions about symptoms, possible diagnoses, tests, and treatment options
    For future appointments:
    • Discuss what was not addressed at the last visit
    • Discuss changes in the quality of life for the patient, family, and caregivers
    • Discuss health goals and other issues in the patient’s and family’s life that may affect the health care decisions
    Take notes during the appointments to help remember what was discussed.
