ABSTRACT: We in vitro examined the existing prognoses of the dissociation constant, KD, between ТАТА- Binding Protein (TBP) and ТАТА box with single nucleotide polymorphism (SNP) associated with human diseases. Five SNPs of the genes for cytochrome P450 2A6 (associated with lung cancer), β-globin (associated with β-thalassemia), mannose binding lectin (associated with variable immunodeficiency), superoxide dismutase 1 (associated with amyotrophic lateral sclerosis) and triosephosphate isomerase (associated with anemia) fell within the range of –ln(KD;M/KD;WT) between –1.5 and –1 (here KD;WT and KD;M denote the normal ТАТА box and with SNP). The mea-surements using EMSA demonstrated that: 1) all the predictions stating that the affinity between ТВР and ТАТА boxes with SNPs would be reduced were correct; 2) the departures of three predictions from the measurements fell within the confidence interval; 3) all the predictions consistently underestimated actual mutational damage caused to ТАТА boxes with SNPs (a
