These people can undergo screening to tell them if they are likely to have the disease later on in life. DNA fingerprinting gives criminal investigators an edge when it comes to solving a wide variety of crimes from burglary to rape. Just a hair left at the crime scene can help in identifying suspects. Paternity testing is very helpful when it comes to single mothers seeking child support and men who want to know if they are actually the biological father of the child. Although there are many pros to genetic screening, there are just as many, if not more, cons to screening.
Financial aspects are one con of screening.
Even though early detection is usually cheaper by means of treatment than later detection, genetic screening is not a small expense and in most or all cases, insurance companies will not cover the expense. Another issue of screening is the idea of privacy. If they find out about this disorder they are likely to drop your coverage, and not many insurance companies will be willing to cover you. Your career may also be in jeopardy if your employer catches wind of your likelihood of a disorder. There are also technical limitations to genetic screening.
