TLDR
The data confirm the previously reported association between LOXL1 polymorphisms and XFG and extend the knowledge to a Central European population.Abstract:
PURPOSE Exfoliation syndrome (XFS) is characterized by an accumulation of abnormal extracellular material in the anterior part of the eye that frequently leads to increased intraocular pressure and glaucomatous optic neuropathy. Recently, two non-synonymous polymorphisms (rs1048661 G>T and rs3825942 G>A) of lysyl oxidase-like protein 1 (LOXL1), a monoamine oxidase that catalyzes the polymerization of tropoelastin to elastin, were found to be associated with increased risk for XFS and exfoliation glaucoma (XFG). The aim of the present study was to investigate the role of these LOXL1 variants in a Central European cohort of Caucasian patients with XFG. METHODS The present case-control study comprised of 167 unrelated patients with XFG and 170 control subjects. Genotyping of the LOXL1 rs1048661 and rs3825942 polymorphisms was done using polymerase chain reaction. RESULTS The frequency of allele G of rs1048661 as well as rs3825942 was significantly higher in patients than in controls (rs1048661: 0.841 in patients versus 0.669; p<0.001; rs3825942: 0.994 in patients versus 0.817; p<0.001). Odds ratios of 52.1 (95% confidence interval [CI]: 13.85-195.6) and 14.67 (95% CI: 3.81-56.2), respectively, were calculated for the two high-risk haplotypes GG and TG compared to the haplotype GA. CONCLUSIONS Our data confirm the previously reported association between LOXL1 polymorphisms and XFG and extend our knowledge to a Central European population.read more

Association of LOXL1 gene common sequence variants in Jordanian patients with exfoliation syndrome and exfoliative glaucoma.
TL;DR: Variations in LOXL1 gene may not be associated with XFS/XFG in the Jordanian population, and more studies are required to confirm the current findings.

TL;DR: There is ample evidence that genetic factors play a major role in the pathogenesis of glaucomas and essentially influence susceptibility and the identification of genetic factors also provides the opportunity to develop novel therapeutic approaches.

TL;DR: The identification and characterization of the B6-Lyst mouse model of XFS, modifiers of Lyst mediated ocular phenotypes, mechanisms of intraocular pressure (IOP) pathology related to circadian rhythms, and mechanisms of iris transillumination defects in the B 6- Lyst mice are presented.

TL;DR: A significant association was found for the G allele of rs1048661 and rs3825942 demonstrating that the GG haplotype is a high-risk factor for the development of PEX syndrome.

TL;DR: Two nonsynonymous SNPs in exon 1 of the gene LOXL1 explain the association with glaucoma, and the data suggest that they confer risk of XFG mainly through exfoliation syndrome (XFS).

TL;DR: It is shown that mice lacking the protein lysyl oxidase–like 1 (LOXL1) do not deposit normal elastic fibers in the uterine tract post partum and develop pelvic organ prolapse, enlarged airspaces of the lung, loose skin and vascular abnormalities with concomitant tropoelastin accumulation.

TL;DR: Findings provide evidence for the systemic nature of the pseudoexfoliation syndrome, which apparently involves an aberrant connective-tissue metabolism throughout the body.

Why is glaucoma associated with exfoliation syndrome
TL;DR: Exfoliation syndrome is an age-related, generalized disorder of the extracellular matrix characterized by production and progressive accumulation of a fibrillar material in tissues throughout the anterior segment and also in connective tissue portions of various visceral organs.
