Britain carefully controls which traits are screened, and regulators are coming under fire for allowing conditions that many people have learned to live with, often with great success.

Henri de Toulouse-Lautrec: Pycnodysostosis, which results in brittle bones that break easily, short stature and abnormal bone growth, particularly of the limbs, skull and jaw
Stephen Hawking: Amyotrophic lateral sclerosis, also known as Lou Gehrig's disease
Stevie Wonder: Blind from infancy because of a destructive ocular disorder
John F. Kennedy: Asthma
Michael J. Fox: Parkinson's disease
Neil Young: Epilepsy
Edwin (Buzz) Aldrin Jr.: Bipolar disorder
