According to the march of times, there are almost 7 babies per 100 newborns who have some birth defect or the other. Out of these birth defects, congenital heart disease, neural tube disorders, neural tube defects, and the cleft lip and the cleft palate are amongst the commonest of birth defects. While the etiology of these defects is manifold ranging from antenatal infection, teratogens, there are a certain percentage of these birth defects that can be caused due to an underlying genetic error, picking up these genetic errors in time has just a benefit not only for the child, because he gets a more comprehensive approach to his condition. But also to the family who would want to know whether their next baby can have the same condition or not.
