Triple X Syndrome

Triple X Syndrome, also known as 47,XXX or trisomy X, is an intersex trait affecting 1 out of every 1000 people assigned female at birth, causing them to have an extra X chromosome (XXX). The most common symptom is taller than average height. In some cases they may also have physical characteristics such as widely spaced eyes, flat feet, and an abnormally shaped breastbone. They may sometimes also experience developmental delays in language skills, as well as motor skills, learning disabilities, seizures, and kidney problems. Most experience little to no noticeable symptoms, and may go most or all of their life not knowing they have it.
