Reduced expression of antigenic proteins MPB70 and MPB83 in Mycobacterium bovis BCG strains due to a start codon mutation in sigK.
This polymorphism, resulting from a T[right arrow]C transition, introduces codon 4 as the start codon resulting in a shorter isoform of the VDR.
The GSTP1 313A[right arrow]G (rs1695), NQO1 609C[right arrow]T (rs1800566), MBL2 codon 54A[right arrow]G (rs1800450), ABCB1 3435C[right arrow]T (rs1045642), MTHFR 677C[right arrow]T (rs1801133), and VDR start codon FokI polymorphism (rs2228570) were genotyped by DNAPrint Genomics (Sarasota, FL) in a multiplex PCR followed by single base extension.
