Single-nucleotide polymorphisms in Rv2629 are specific for Mycobacterium tuberculosis genotypes Beijing and Ghana but not associated with rifampin resistance.

Sequence analysis of 58 multidrug-resistant Mycobacterium tuberculosis complex strains from Germany and 55 susceptible strains from a reference collection comprising major phylogenetic lineages confirmed that variations in Rv2629, 191A/C and 965C/T, are specific for genotypes Beijing and Ghana, respectively, but not involved in the development of rifampin (rifampicin) resistance.
