[Association between LOXL1 gene polymorphisms and primary open angle glaucoma in Sichuan population]
1Sichuan Key Laboratory for Disease Gene Study, Sichuan Academy of Medical Sciences, Sichuan Provincial People's Hospital, Chengdu, Sichuan 610000, P. R. China.
Summary
This study found no association between specific lysyl oxidase-like 1 (LOXL1) gene single nucleotide polymorphisms (SNPs) and primary open-angle glaucoma (POAG) in the Sichuan population. Further research is needed to understand POAG genetic risk factors.
Area of Science:
- Genetics and Ophthalmology
Background:
- Primary open-angle glaucoma (POAG) is a leading cause of irreversible blindness worldwide.
- The lysyl oxidase-like 1 (LOXL1) gene has been implicated in glaucoma pathogenesis in some populations.
Purpose of the Study:
- To investigate the association between specific single nucleotide polymorphisms (SNPs) in the LOXL1 gene and POAG.
- To determine if rs1048661, rs3825942, and rs2165241 LOXL1 SNPs are risk factors for POAG in the Sichuan population.
Main Methods:
- A case-control study was conducted with 416 POAG patients and 997 healthy controls from the Sichuan region.
- Genotyping of three LOXL1 tag SNPs (rs1048661, rs3825942, and rs2165241) was performed using the SNaPshot method.
Main Results:
- No statistically significant differences were observed in the genotype frequencies of the studied LOXL1 SNPs between POAG cases and controls.
- Allele frequency distributions for rs1048661, rs3825942, and rs2165241 did not differ significantly between the POAG and control groups.
Conclusions:
- The investigated LOXL1 SNPs (rs1048661, rs3825942, and rs2165241) are not associated with POAG in the Sichuan Chinese population.
- These findings suggest that LOXL1 genetic variations may not play a significant role in POAG development in this specific ethnic group.

20.3K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

44.4K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

17.1K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

1.7K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:27Open Angle Glaucoma: Treatment
1.1K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
