Potential Mutations in Chinese Pathologic Myopic Patients and Contributions to Phenotype

Area of Science:

• Ophthalmology
• Genetics
• Molecular Biology

Background:

• Pathologic myopia is a significant cause of vision loss, particularly in East Asia.
• Understanding the genetic basis of pathologic myopia is crucial for developing effective treatments.

Purpose of the Study:

• To investigate potential gene mutations in Chinese patients with pathologic myopia.
• To analyze the correlation between identified genotypes and clinical phenotypes.

Main Methods:

• Recruited 103 patients with pathologic myopia and 109 healthy controls.
• Collected clinical data including imaging, visual acuity, axial length, and refractive error.
• Performed high-throughput DNA targeted sequencing and analyzed phenotype-genotype correlations.

Main Results:

• Identified six potential pathogenic mutations: PEX7, OCA2, LRP5, TSPAN12, RDH5, and TTC21B.
• OCA2 mutations were predominantly found in patients with myopic traction maculopathy.
• Detailed clinical data and genetic variants were analyzed across patient subgroups.

Conclusions:

• Genetic alterations play a role in the diverse clinical manifestations of pathologic myopia in Chinese patients.
• The findings may offer new perspectives on the etiology of pathologic myopia.
• Potential therapeutic targets for pathologic myopia may be identified through this research.
