Nail patella syndrome is a rare genetic condition that can cause problems with the nails, bones, kidneys and eyes. It's thought to affect at least1 in 50,000 people.

Symptoms vary, but almost everyone with the condition will have abnormal nails and many also have problems with their elbows, knees and pelvis. However, most people are able to lead relatively normal lives.
