Myths vs facts: Cardio Risk Check | Herz-Kreislauf Risiko-Test and blood sugar

The myth that a single DNA test can fully predict cardiovascular risk is misleading. Tests like MyBody-X Cardio Check analyze specific SNPs (e.g., rs7903146 in TCF7L2 for blood sugar regulation, rs662799 in APOA5 for triglycerides). These variants show statistical associations (GWAS), but effect sizes are small and often overshadowed by lifestyle factors (diet, exercise, smoking). Blood sugar is a key but not sole risk factor – it interacts with genetics, insulin resistance, and inflammation markers. Such tests cannot diagnose; they only indicate predispositions. Evidence is mixed: solid GWAS data, but no clinical validation as a standalone screening tool. Beware of exaggerated marketing claims. A comprehensive risk profile requires classic biomarkers (lipids, blood pressure, HbA1c) and medical evaluation.
