Genetic counseling, costing a few hundred dollars, is a lower-cost preventative alternative to expensive gene therapies for informing individuals about their risk of passing on genetic diseases to their children.

“An alternative to this expensive solution is a much lower cost one, which is genetic counseling, where you basically tell people before they get married, before the preconception or sometimes post-conception, that they're at risk. They themselves are carriers. They are healthy. They will be healthy. But if they marry someone that has the same carrier status, they put their children at risk.”
