¿Existe riesgo de deformidades si los primos segundos se casan?

Existe un riesgo insignificante de defectos de nacimiento en los hijos de primos segundos que se casan. While the risk of birth defects is theoretically doubled compared to unrelated parents (from 2-3% to 4-6%) this small increase is not enough to warrant significant concern. Some families have a higher incidence of a specific genetic disorder, so if there are known hereditary conditions in your family, it would be wise to consult with a genetic counselor before making a decision about marriage.
