'Some of them have accuracy that's close to zero': Experts unpack the promise and pitfalls of genetic tests aimed at consumers
Live Science • • general
Key Points:
- The book "What We Inherit" by Daphne Martschenko and Sam Trejo examines myths and misconceptions about genetics, emphasizing the need for regulation of genomic technologies like direct-to-consumer genetic tests and polygenic embryo selection to prevent social inequalities.
- The authors challenge the "destiny myth," the false belief that DNA alone determines traits and life outcomes, highlighting that genetic influences are complex, polygenic, and intertwined with social and environmental factors.
- Polygenic scores show promise in medical contexts, such as assessing disease risk to guide treatments, but their use in non-medical areas like embryo selection or private school admissions raises ethical concerns and lacks robust scientific backing.
- Direct-to-consumer genetic tests often lack transparency and scientific rigor, sometimes offering
