Comparative analysis of the frequency of SNPs in the mce operons genes of drug resistant (DR) and drug sensitive (DS) clinical isolates. SNPs were explored using Sequenom MassARRAY platform. DR (n = 59) and DS (n = 22) clinical isolates of M. tuberculosis were taken up for this study. The comparison between the two categories revealed that (A) mce1 and (B) mce4 operon genes were significantly more polymorphic in DS clinical isolates than DR isolates (*, p < 0.05) and (**, p < 0.01) respectively.
