Fetal genetic problems may arise in three ways: they can be passed from father or mother, may occur as a result of damage to the egg or sperm or because of damage to the fetus at an early stage pregnancy. We talk about the first case, where abnormal gene is inherited, that is, when the blame heredity. In the second and third cases to blame the environment: random genetic mutations are caused by something in the environment – Your or your partner – before conception or in the environment of the fetus during pregnancy. Recently Kidney Foundation sought to clarify these questions. The best way to minimize the risk of such problems will seek advice before conception, to draw attention to their diet and intake of vitamins and certain way to change their habits. Avoiding alcohol, stimulating pills, avoidance of infections (such as rubella, syphilis, and cytomegalovirus) and harmful to the child medicines also help prevent a large percentage of these inherited genetic problems: neural tube defects (NTDs): neural tube, which develops in the brain and spinal cord and nerves, formed by 4 weeks of pregnancy, often when you have not yet realized that you are pregnant. NTDs can happen in 1 in 1000 births, but the likelihood is increased if you already had a child with NTDs (1% probability) or if you or your spouse has a personal history of NTDs (2-3% probability)..
