Pairwise comparison of the serum lysozyme levels between the patients with presumed sarcoidosis and presumed latent syphilis revealed a statistically significant difference for presumed sarcoidosis with the p value 0.033 which was also greater than the p value of pairwise comparison of the serum ACE levels between patients with presumed sarcoidosis and presumed latent syphilis. The gene discussed is LYZ; the disease is sarcoidosis.
