Shared Genetic Variants in Two Types of Strabismus Offer Hope for Future Treatments

Researchers at Boston Children’s Hospital have made a significant discovery regarding the genetics of strabismus, a condition affecting eye alignment. They found that two types of strabismus, esotropia and exotropia, may share genetic risk factors. Specifically, duplications on the second, fourth, and tenth chromosomes were identified in patients with both conditions. This breakthrough suggests a shared underlying genetic cause for both types of strabismus, offering hope for developing treatments that could benefit sufferers of either condition.

The study involved genetic samples from 234 patients over 18 years, including individuals with exotropia and their family members, some of whom had strabismus and others who did not. The research, published in JAMA Ophthalmology, highlights the significant role of genetics in strabismus, despite known environmental risk factors like prematurity and smoking during pregnancy.

This research is a great find in understanding the genetics of strabismus. By discovering the common genetic factors that cause different types of the condition, scientists are opening up opportunities for more specific treatments and ways to prevent it. More studies to understand how it all works could lead to significant advancements in eye care.
