If a baby displays any symptoms of Cri Du Chat syndrome, the most common being the cat cry, or if a parent has the disorder, testing is usually performed in order to assess whether or not the baby has Cri Du Chat Syndrome. To do this, a test called chromosome analysis in which doctors look at the chromosomes under a microscope may be ordered. However, if the deletion of the chromosome is too small to see, a more detailed test is performed. This test, FISH, or fluorescence in-situ hybridization, detects the smaller deletions on Chromosome 5.
If the baby does have Cri Du Chat Syndrome, a number of things can be done. If the child suffers from mental retardation, many believe that therapy may help. However, there is as of yet no cure for Cri Du Chat Syndrome.
