Humans need an intact X chromosome to survive. When all (or part) of the second sex chromosome-the X or the Y chromosome-is absent, a characteristic prenatal and postnatal phenotype results. Of the small percentage that survives to term, affected individuals are phenotypic females with dysgenetic ovaries, short stature, and other typical but highly variable dysmorphic features (Fig. 1).
