[Rational use of genetic tests in internal medicine : Possibilities and limitations of next generation sequencing diagnostics].

BACKGROUND

New methods of molecular genetic diagnostics enable a more comprehensive genetic analysis of patients.

OBJECTIVES

Rational use and benefits of molecular genetic testing in patients with various internal diseases.

METHOD: Evaluation of topic-related literature, discussion of own experiences, as well as consideration of current guidelines.

RESULTS

New genetic tests, such as next generation sequencing (NGS), improve the diagnosis of hereditary diseases; however, the use of this technology also leads to additional findings, which must be carefully considered.

CONCLUSION

The rational use of genetic tests is a benefit for patients and can significantly influence the prevention and treatment of a disease. The increasing complexity of genetic findings requires interdisciplinary approaches involving human genetics, internal medicine, and other disciplines.
