Which advice would you give to someone who has just been diagnosed with Gillespie syndrome?

Gillespie syndrome is a rare genetic condition characterized by partial aniridia (absence of part of the iris), ataxia, and intellectual disability, usually caused by mutations in the PAX6 gene. Receiving a diagnosis of Gillespie syndrome can be overwhelming, but your best path forward involves building a multidisciplinary care team, prioritizing early developmental support, and connecting with a community that understands your unique journey.

What is the most important advice for someone newly diagnosed with Gillespie syndrome?

The most important step after a diagnosis of Gillespie syndrome is to shift your focus toward comprehensive, multidisciplinary management. Because Gillespie syndrome is a multisystem condition, you should not rely on a single physician. Instead, seek a "medical home"—a primary care provider or geneticist who coordinates care between ophthalmologists, neurologists, and developmental specialists. Remember that while this diagnosis is life-changing, it does not define your or your loved one's entire future; focusing on individual strengths and early intervention services is key to improving long-term outcomes.

How should I build my medical care team?

Building an effective care team for Gillespie syndrome requires specialists who are familiar with neuro-ophthalmology and genetic disorders. Your team should ideally include:

• Ophthalmologist: To manage the partial aniridia and monitor for secondary complications like glaucoma or cataracts.


• Neurologist: To assess and manage the non-progressive ataxia and provide supportive therapy.


• Clinical Geneticist: To provide ongoing counseling regarding the PAX6 gene mutation and its implications for family planning.


• Developmental Pediatrician or Therapist: To coordinate physical, occupational, and speech therapy, which are vital for managing the developmental delays associated with Gillespie syndrome.

How can I manage daily life and find community support?

Managing the daily impact of Gillespie syndrome often involves adapting the environment to account for visual sensitivities and motor coordination challenges. Many families find that visual aids and mobility support significantly enhance independence. You are not alone in this; currently, 9 people with Gillespie syndrome have joined the DiseaseMaps community. Connecting with these individuals can provide emotional validation and practical tips that you won't find in textbooks. Sharing your experience with others who truly understand the daily realities of Gillespie syndrome is one of the most powerful tools for mental well-being.

How do I stay informed about research and financial support?

Navigating the healthcare system can be daunting, but resources exist to help ease the burden. For financial assistance and disability benefits, contact your local rare disease advocacy groups, which often provide guidance on navigating government assistance programs. To stay informed about the latest research on Gillespie syndrome, regularly monitor the NIH Genetic and Rare Diseases (GARD) Information Center and participate in patient registries. These registries are essential for researchers to understand the natural history of the condition, which is a necessary precursor to developing future treatments.

Next steps

• Consult a clinical geneticist to confirm the PAX6 mutation and discuss potential implications for family members.


• Join the DiseaseMaps.org community to connect with other families living with Gillespie syndrome.


• Request a referral to a pediatric or adult neurologist who specializes in movement disorders or ataxia.


• Begin an early intervention assessment to identify which therapies (PT, OT, or Speech) will be most beneficial.
