The protein encoded by this gene is a beta-galactoside-binding lectin that functions as a cellular sensor of membrane damage, detecting pathogens by binding to exposed galactoside ligands and targeting them for autophagy to restrict bacterial and viral infections. This gene has very low constraint against loss-of-function variants (pLI near 0, LOEUF >1), and no established Mendelian diseases have been associated with LGALS8 mutations to date. The gene is widely expressed and involved in cell adhesion, growth regulation, and immune defense mechanisms.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
