Whilst surgery is the primary treatment for cataracts, it is not always an available option, particularly in developing countries. Non-surgical methods of treatment would increase treatment availability for more patients. Several studies have investigated how topical application of oxysterols, such as lanosterol, may break down aggregated proteins and restore lens transparency. However, the results are conflicting and inconclusive.<\/jats:p><jats:p><jats:bold>Aim:<\/jats:bold> In this study, we focus on combining genetic evidence for associations between lanosterol related genetic variation and cataract to explore whether lanosterol is a potentially suitable drug treatment option.<\/jats:p><jats:p><jats:bold>Method:<\/jats:bold> Using data from 45,449 available cataract cases from the UK Biobank, with participant ages ranging from 40\u201369, we conducted a genetic association study (GWAS) to assess the risk of cataract. Cataract cases were defined using diagnostic and operation codes. We focused on genetic variants in the lanosterol synthase gene region. We also compared our results with previously published genetic associations of phytosterol-to-lanosterol ratios. Finally, we performed a genetic risk score analysis to test the association between lanosterol within the cholesterol synthesis pathway and the risk of cataract.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> No statistically significant single nucleotide polymorphisms (SNPs) associations with cataract were observed in the gene region of lanosterol synthase at a multiple testing adjusted significance threshold of <jats:italic>p<\/jats:italic> &amp;lt; 0.05\/13. The comparison between cataract risk and genetic association of 8 phytosterol-to-lanosterol GWAS results also showed no evidence to support lanosterol\u2019s protective properties for cataract risk. No statistically significant association was found between the lanosterol within the cholesterol synthesis pathway genetic risk score and cataract outcomes (OR = 1.002 <jats:italic>p<\/jats:italic> = 0.568).<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> There was no evidence observed for genetic associations between lanosterol and cataract risk. Our results do not support lanosterol\u2019s potential role in treating cataracts. Further research may be needed to address the effect of lanosterol on specific cataract subtypes.<\/jats:p>","DOI":"10.3389\/fgene.2024.1231521","type":"journal-article","created":{"date-parts":[[2024,2,19]],"date-time":"2024-02-19T10:57:18Z","timestamp":1708340238000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Using genetics to investigate the association between lanosterol and cataract"],"prefix":"10.3389","volume":"15","author":[{"given":"Munisa","family":"Hashimi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hasnat A.","family":"Amin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Loukas","family":"Zagkos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander C.","family":"Day","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fotios","family":"Drenos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2024,2,19]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"123","DOI":"10.1016\/j.hlpt.2012.07.003","article-title":"UK Biobank: current status and what it means for epidemiology","volume":"1","author":"Allen","year":"2012","journal-title":"Health Policy Technol."},{"key":"B2","doi-asserted-by":"publisher","first-page":"655","DOI":"10.1134\/s0006350918040024","article-title":"Lanomax as a drug in cataract treatment: a case study","volume":"63","author":"Balashova","year":"2018","journal-title":"Biophysics"},{"key":"B3","doi-asserted-by":"publisher","first-page":"420","DOI":"10.1136\/bjo.2006.106724","article-title":"Outcomes of cataract surgery in Pakistan: results from the Pakistan national blindness and visual impairment survey","volume":"91","author":"Bourne","year":"2007","journal-title":"Br.
