Web8.1.4 Adherence to Hardy-Weinberg distribution. The quality control based on Hardy-Weinberg (H-W) distribution is a bit trickier to explain. You might know the definition of the Hardy-Weinberg rule from population genetics which states that genetic variation (thus allele and genotype frequencies) in a population will remain constant unless certain disturbing … WebJul 1, 2012 · Abstract. Background and aims: A pre-treatment determination of the thiopurine S-methyltransferase (TPMT) genotype or phenotype can identify patients at risk of developing severe adverse reactions from thiopurine treatment. The risk of misclassifying a patient might be dependent on the method used. The aim of this study was to investigate …
