BACKGROUND: Aicardi-Goutières syndrome (AGS) is a rare autosomal recessive encephalopathy of early onset. AGS visual dysfunction range from nystagmus and optic atrophy to cortical blindness in affected individuals; however, congenital glaucoma has been recently noticed among AGS pediatric patients. According to the literature, aniridia has never been recognized among AGS patients.
CASE REPORT: We report the case of a 4-year-old boy with AGS who had multiple congenital anomalies in the eyes. He was found to have congenital glaucoma, nystagmus, spherophakia with shallow chambers, and aniridia in both eyes. Family history was positive for glaucoma, with consanguineously married parents. According to the genetics report, both parents are carriers of congenital glaucoma genes. A whole-exome sequencing identified IFIH1 heterozygous missense mutation of the patient, which is associated with AGS Type 7. Also, he was diagnosed as having congenital glaucoma with CYP1B1 mutation, homozygous recessive. This case demonstrates the unusual coexistence of bilateral aniridia, a feature not previously reported in ocular findings of AGS.
CONCLUSIONS: In summary, this is the first reported case of aniridia with AGS-related congenital glaucoma in the literature. This paper summarizes the usual ocular manifestation of AGS, also it highlights atypical ocular features in both; AGS as well as congenital glaucoma. The aim of this paper is to lay the foundation for a national database on AGS in Saudi Arabia, which will help create a bridge between genetic data and clinical findings of AGS patients.
