If they receive the additional X chromosome from their parent's original sperm or egg cell, they will have 47XXX chromosomes in all their cells. If the additional chromosome appears during the embryo's development process, however, only some cells will have 47XXX chromosomes and the person will be born with a mosaic chromosome pattern. Most people with 47XXX chromosomes do not develop any variations in their other sex characteristics but some may have ovaries that stop producing hormones at an earlier-than-typical age and some may not menstruate.
