β3GnT2^−/−mice retain the majority of their olfactory discriminatory ability. Mice were tested against pairs of odors for their ability to associate odor with a food reward. β3GnT2^−/− mice can discriminate two of the odors, citralva and β-ionone as well as wild type controls. There is a significant (asterisks) reduction in the ability of null mice to discriminate geraniol, citronellal, decanal, and 3-n-hexylpyridine, but the differences are small and highly variable.
