was kostet ein gentest erbkrankheiten — what are common causes?

Costs for genetic tests for hereditary diseases vary widely: single-gene tests (e.g., BRCA1/2) often cost €200–500, while comprehensive panels or exome sequencing can range from €1,000 to €3,000 or more. In Germany, statutory health insurance covers costs only if there is a justified suspicion (e.g., family history). Direct-to-consumer tests (like MyBody-X) are cheaper (approx. €100–300) but are not diagnostic and typically cover only selected risk variants – not a full analysis of all hereditary diseases. Common causes of hereditary diseases include mutations in single genes (e.g., CFTR in cystic fibrosis, HBB in sickle cell disease, BRCA1/2 in breast cancer) or chromosomal abnormalities. The predictive value of home tests is limited; a negative result does not rule out disease. For serious concerns, genetic counseling is recommended.
