In fact, the significance of genetic counseling and genetic testing is not only for couples or families who have no clear medical history, but also for those who have one of the above situations, and do the necessary genetic testing according to the doctor's advice. Some couples gave birth to babies with genetic diseases, and in genetic counseling, they misunderstood the correct meaning of recurrence risk rate. For example, the genetic incidence of a genetic disease is 50%. Some couples think that when they give birth to such a baby, the genetic proportion will be much smaller when they have another baby. In fact, every time a couple gives birth to a baby, there is a 50% chance of suffering from this genetic disease, and the risk of recurrence will not be reduced because they have given birth to one or even two such babies.
