Isolated anophthalmia and microphthalmia in a newborn with ALDH1A3 mutation
Author: Mário Lima Fontes
ePoster Number: 292
Purpose
This work aims to present the clinical case of a newborn with right anophthalmia and a concomitant left microphthalmia.
Methods
Analysis of a case report.
Results
A newborn was referred to a pediatric appointment due to a prenatal diagnosis of a bilateral ocular malformation. At observation, there was no evidence of the right eye, and a mass was found on the left orbit. Orbital ultrasound, CT and MRI examination confirmed the absence of the right globe and the presence of a cystic lesion in the left orbit. Both the newborn and the mother serologies were negative for microorganisms of the TORCH group. The genetic study revealed two probable pathogenic variants in the aldehyde dehydrogenase 1 family, member A3 (ALDH1A3) gene. At 3 months old, an expander was placed in the right orbital cavity. One year later, the cystic lesion in the left orbit was excised and the anatomopathological examination revealed that it was in fact the remnants of the eye. An expander was also placed in the left orbit. The patient is currently being followed in ophthalmology, pediatrics and physical rehabilitation appointments and does not present signs of other systemic malformations.
Conclusion
Anophthalmia and microphthalmia are early-eye-development anomalies resulting in absent or small ocular globes, respectively. The combined birth prevalence of these conditions is up to 30 per 100,000 population. Mutations in the ALDH1A3 gene have been found in association with autosomal recessive anophthalmia and microphthalmia in individuals of different ethnicities, typically from consanguineous families. ALDH1A3 is a key enzyme in the formation of a retinoic acid gradient along the dorsoventral axis during early eye development. This clinical case shows autosomal recessive anophthalmia and microphthalmia in a newborn with ALDH1A3 mutation and non-related parents.
