The newest and most sophisticated of the techniques used to test for genetic disorders, involve direct examination of the DNA molecule itself. How does it work? Doctors scan a patient's DNA (obtained from any tissue or blood) for any mutated sequences. For some types of tests researchers design short pieces of DNA called probes, whose sequences are complementary to the mutated sequences. These probes will seek their complement among the three billion base pairs of an individual's genome. If the mutated sequence is present in the patient's genome, the probe will bind to it and flag the mutation. Another type of DNA testing is comparing a patient's DNA bases to those of a normal version of genes. What diseases does genetic testing test for? Currently, there are over 1,000 diseases that are able to be genetically tested for. A few explained examples of genetically tested diseases are: How much
