Doctor's answer:
There are two main causes of fetal malformation: one is genetic gene defects leading to fetal malformation, which is most likely to occur in cases of consanguineous marriage or marriage between individuals with family hereditary diseases; the other is non-genetic gene defects causing fetal malformation, which is often due to the neglect of teratogenic factors by the pregnant woman during pregnancy.
