Correlation between polymorphisms in the MFN1 gene and myopia in Chinese population

Area of Science:

• Ophthalmology
• Genetics
• Molecular Biology

Background:

• Myopia, or nearsightedness, is a prevalent refractive error with complex genetic and environmental influences.
• Understanding the genetic underpinnings of myopia is crucial for developing effective prevention and treatment strategies.
• The mitofusin 1 (MFN1) gene plays a role in mitochondrial dynamics, which may be implicated in ocular development and function.

Purpose of the Study:

• To investigate the association between genetic variations in the MFN1 gene and the risk of developing low to moderate myopia.
• To analyze specific single nucleotide polymorphisms (SNPs) within the MFN1 gene in a Chinese population.

Main Methods:

• A case-control association study was conducted with 100 myopia patients and 100 healthy controls.
• Four tag SNPs (rs3976523, rs13098637, rs6762399, and rs7618348) in the MFN1 gene were selected and genotyped.
• Genotype and allele frequencies were compared between cases and controls using the Chi-square test.

Main Results:

• Genotype distributions for all four SNPs were in Hardy-Weinberg equilibrium.
• The SNP rs13098637 showed a statistically significant association with low to moderate myopia (P=0.003).
• No significant associations were found for the other three SNPs (rs3976523, rs6762399, rs7618348).

Conclusions:

• The C allele of MFN1 rs13098637 is significantly associated with low to moderate myopia in the studied Chinese population.
• This finding suggests a potential role for MFN1 genetic variations in myopia pathogenesis.
