This woman likely has Triple X syndrome, also known as Trisomy X. This condition often does not have any noticeable physical or developmental abnormalities. However, some girls and women with this syndrome may be slightly taller than average. They may also have some learning and language difficulties. They are generally able to reproduce and are not sterile. Facial hair and apparent male characteristics are not typically associated with Triple X syndrome.
