What do studies say about DNA Test Kinder?

DNA tests for children are often marketed to predict talents, athletic abilities, or health risks, but the scientific evidence is limited. Most traits are polygenic and heavily influenced by environment and lifestyle. Single-gene variants like ACTN3 or COMT have very small effect sizes (OR ~0.01–0.17) and explain little variance. Polygenic risk scores are poorly transferable to non-European populations, and longitudinal studies in children are lacking. Ethical concerns include labeling, anxiety, and false expectations. The evidence is unclear; these tests are not clinically validated. Parents should not base medical or educational decisions solely on such tests.
