Application of molecular genetic methods in the diagnosis and treatment of human diseases is extremely wide due to a huge amount of hereditary information contained in the human genome. Gene diagnostics allows establishing predisposition to diseases, identification of genetic abnormalities and prediction of pathological outcomes. In addition, gene diagnostics also enables prediction of the individual response to treatment in order to achieve the maximum therapeutic effect. Among all molecular genetic methods, polymerase chain reaction (PCR) diagnostics is a leading approach. Technical simplicity, low cost, high sensitivity and reliability of the method have made PCR diagnostics a routine modality for the risk assessment, diagnostics, and monitoring of the treatment efficiency. Here, we consider the application of PCR diagnostics for the abovementioned tasks and talk about the real-life examples of detecting mutations and chromosomal aberrations which may cause a disease. Further, we discuss the prospects of using a semi-quantitative PCR in medical practice and focus on pharmacogenetics as a key component of a personalised therapy. The lecture is aimed primarily at biomedical students and physicians and represents a continuation of the previous lectures published in Fundamental and Clinical Medicin.
