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

The question of myths vs facts regarding cardiovascular risk tests and blood sugar is important. A common myth is that a DNA test alone can reliably predict your heart attack or diabetes risk. Fact: Genetic variants like APOE4 (rs429358) are moderate risk factors for cardiovascular disease and Alzheimer's, but not deterministic. The effect is moderate and modifiable by lifestyle. APOA1 variants have only small effects on HDL function; DTC tests cannot measure actual cholesterol efflux. For blood sugar, ADRB3 (rs4994) shows a small influence on obesity risk, but no guarantee. The marker rs10913469 (SLC2A5) for fructose malabsorption is clinically unclear and not diagnostic. Evidence is mixed: strong for APOE4 (human GWAS), moderate for APOA1 and ADRB3, unclear for rs10913469. The gold standard remains clinical biomarkers like lipid panel, HbA1c, and fasting glucose. Do not be misled by exaggerated DTC claims; consult a physician before changing diet or medication based on genetic data alone.
