The Controversy of Genetic Embryo Screening

The Rise of Genetic Screening

As technology advances, companies like Herasight and Nucleus Genomics are offering parents the ability to choose traits for their embryos. This controversial practice, known as polygenic embryo screening, estimates the likelihood of various health risks and even physical traits such as height and IQ.

• Key features of genetic embryo screening include:
• Health risk assessments for diseases like cancer and diabetes.
• Predictions on traits such as eye color and BMI.
• The use of polygenic risk scores to guide embryo selection.

Despite the allure of 'designer babies', medical experts caution that the science behind these screenings is still evolving. Organizations like the American College of Medical Genetics emphasize that environmental factors also play a significant role in health, raising questions about the ethics and reliability of such genetic predictions.
