However, the general principles are the same for all the types - the difference with bead arrays is that the probes need to be identified, whereas on oligo arrays the probes are printed on fixed locations on the array surface. This example uses sample data from the E. coli Antisense Genome Array. The Food and Drug Administration in January 2014 cleared a first-of-a-kind whole-genome postnatal blood test that can aid physicians in identifying the underlying genetic cause of developmental delay, intellectual disability, congenital anomalies, or dysmorphic features in children, where it was noted that "[a]bout 2 to 3 percent of U.S. children have some sort of intellectual disability, according to the National Institutes of Health.
