WebA microdeletion is an abnormality that occurs when a piece of a chromosome is missing. In fact, it’s just what it sounds like: micro (tiny); deletion (taken away). You might remember from high school biology that virtually all of our cells contain chromosomes with DNA; we get 23 from each parent for a total of 46. WebLater, the developers of the DNA microarray dotted an array of DNA copies (cDNAs) corresponding to a large number of different mRNAs of known sequence onto a glass … WebWhat does a negative or normal chromosomal microarray (aCGH) result mean? A negative result means that the chromosomal microarray test did not detect a significant deletion or duplication in the chromosomes of the fetus.
