Either that or adoption or artificial fertilization. Or they decide to get children anyway.

But at least they can consult with a doctor and make an informed decision whether to take the risk or not.

Another example is Thalassemia, a sickness where blood cells have a different structure, protecting the affected from malaria.

Unfortunately, if 2 people with thalassemia (minor) have a child, there will be a 25% chance the kid will have a for of thelassaemia major, which means they need a blood transfusion every few months, otherwise they will die.

This is why in countries where malaria is prevalent, couples are encouraged to do a blood screening before having children to prevent this scenario.
