Gillespie syndrome, a genetically inherited condition, is described as a disease that primarily affects the ocular and associated nervous systems. It is characterized by a clinical triad of bilateral aniridia, intellectual disability, and cerebellar ataxia, and is inherited in an autosomal dominant or recessive fashion. The most well-studied mutations related to this syndrome affect the inositol 1,4,5-trisphosphate receptor type 1 gene (ITPR1). Gillespie syndrome is an exceptionally uncommon diagnosis with less than 50 patients ever being diagnosed. We present a case of a patient with bilateral aniridia and ataxia but lacking intellectual disability, and moreover had no known family history of this syndrome. Our case report shows that Gillespie syndrome may not necessarily present with the classic "triad" of symptoms as previously described in the literature.
