wie viel gene hat der mensch — when to see a doctor?

The human genome contains approximately 20,000–25,000 protein-coding genes (as of 2023), plus thousands of non-coding RNA genes and regulatory elements. The exact count is fluid because the definition of a 'gene' is evolving. When to see a doctor: If you receive a genetic test result (e.g., from MyBody-X) indicating increased risk for inflammation or autoimmune disease, that is not a diagnosis. These tests often report small-effect single SNPs. If you have symptoms like fatigue, joint pain, or unexplained inflammatory markers, a doctor's visit is essential. Similarly, a home TSH test showing 2.5 mIU/L is within normal range but cannot rule out subclinical thyroid issues; a full thyroid panel by a physician is needed. For children's sleep problems, behavioral or medical causes are far more common than genetic ones. In summary: genetic tests can provide clues but not diagnoses. Always consult a doctor for health concerns or abnormal test results.
