The pair of sex chromosomes, X and Y, are a little different. When there are too many or two few chromosomes, or missing or extra pieces of chromosomes, there can be a problem with a baby s development. Sometimes, these problems are fatal or can affect a child s ability to walk, talk or learn. Other times, the abnormalities cause more mild or subtle problems. Working with cytogeneticists and genetic counselors, clinical geneticists interpret abnormal karyotypes, and provide guidance and support to the parents.
Many parents look to amniocentesis for reassurance.
In every pregnancy there is a chance that the fetus may have an extra or missing chromosome. Many times, if there is an extra or missing chromosome, the pregnancy miscarries naturally because normal development cannot take place. The exciting news about the AneuVysion Test is that it answers specific, urgent questions about the fetus. The AneuVysion Test is not intended as a stand-alone test for making clinical decisions. The AneuVysion Test uses colored DNA probes that attach to specific chromosomes in the fetal cells.
