Symptoms are from problems in a baby’s chromosomes. These are the packages of genes inside a cell.
There are many syndromes that can result from these abnormalities. Each has its own signs. Some signs are poor growth, intellectual disability, learning problems, and problems with structures like the heart.
For a couple attempting to have a child, having at least two miscarriages may be a sign of an abnormality. Talk to your doctor about testing. The results are normal in most cases. If the results are not normal, you and your partner should meet with a geneticist.
