wie viele gene hat der mensch — which blood markers matter?

The number of human genes is currently estimated at about 20,000–25,000 protein-coding genes, based on the Human Genome Project and ongoing annotations (e.g., GENCODE). Thousands of non-coding RNA genes exist, bringing the total transcribed gene count potentially to 60,000. Regarding which blood markers matter, the context from MyBody-X highlights several clinically relevant ones: iron status (ferritin, transferrin saturation) for HFE variants (C282Y, H63D), vitamin D levels given genetic risk factors, and blood lipids (triglycerides, LDL) in relation to lipid genes like rs662799. Inflammatory markers (hs-CRP) and fasting glucose are also important for personalized health assessment. Caveat: home tests provide screening insights, not diagnoses. Blood markers must be interpreted in clinical context with medical guidance. Evidence for gene count is strong; for blood marker selection it is based on practice guidelines and observational studies.
