Nail Patella Syndrome UK What is NPS

Description: Nail Patella Syndrome (NPS) also known as NPS, Fong disease, hereditary onycho ­osteodystrophy (HOOD), Osterreicher-Turner syndrome and Turner-Kieser Syndrome. Nail Patella Syndrome is a genetic condition which affects the nails, knees, elbows and can cause iliac horns. There are, however, many other features that may be seen in this condition and other body systems such as the kidneys and eyes may be affected. In the skeletal system, tendons, ligaments and muscles can be affected as well as bones. The severity of the features of NPS and how often each feature occurs, varies between one person with NPS and another, even within the same family. Patients may be severely affected by one aspect of NPS but have much milder or no problems elsewhere. A patient with NPS does not have to have all of the features of the condition. It is very common for families to remain undiagnosed for several generations despite having been seen by doctors from a variety of disciplines. It is thought that NPS occurs in 1 in 50,000 people.
