Summary
Genetic factors influence high myopia (HM). A specific single nucleotide polymorphism (SNP), rs17036350 in the MTOR gene, is associated with HM and axial length in the Han Chinese population.
Area of Science:
- Ophthalmology
- Genetics
- Molecular Biology
Background:
- High myopia (HM) is a significant global ocular disorder with strong genetic underpinnings.
- Understanding the genetic factors contributing to HM is crucial for developing effective management strategies.
Purpose of the Study:
- To investigate the association between candidate single nucleotide polymorphisms (SNPs) and high myopia (HM) in the Han Chinese population.
- To explore the functional role of identified SNPs in the mechanisms of HM development.
Main Methods:
- A case-control study involving 1008 Han Chinese participants (508 HM patients, 500 controls).
- Genotyping of 11 candidate SNPs using multiplex PCR and high-throughput sequencing.
- Functional annotation and validation in a mouse model of myopia.
Main Results:
- The SNP rs17036350 in the Mechanistic Target of Rapamycin Kinase (MTOR) gene was significantly associated with HM in the Southern Han Chinese population.
- This SNP showed a correlation with increased axial length (AL) in HM patients, particularly in females.
- Bioinformatic analysis indicated rs17036350's role in MTOR gene regulation, and elevated p-mTOR levels were observed in a myopia mouse model.
Conclusions:
- rs17036350 within MTOR may serve as a genetic marker for HM and is associated with axial elongation.
- MTOR activation appears to play a role in the axial elongation observed in myopia.
- These findings offer insights into myopia's genetic regulation and potential therapeutic targets.

mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

PI3K/mTOR/AKT Signaling Pathway
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a rapamycin-insensitive companion...
