Fatty acyls. We found significant inverse associations of fatty acyls and GRS8, GRS2, and LOXL1 SNP rs3825942G allele, which suggests that fatty acyls may be linked to a lower genetic susceptibility of XFS, and indicate a potential protective role in XFGS/XFG pathogenesis. The gene discussed is LOXL1; the disease is exfoliation syndrome.
