An absence or immature kneecaps and thumbnails are responsible to cause Nail Patella Syndrome in an individual. Statistics of government agencies and hospitals says that one in every 50000 newborn babies is affected by this disease.
Scientists have established the close relation between glaucoma and nail patella syndrome. At several circumstances it has been found that a newborn affected with this rare disorder has no thumbnails or underdeveloped thumbnails. The mother of such babies and other family members has also found with an absence of thumbnails in most of the medical examinations. However, it is not clear yet, whether glaucoma directly relates to the mutation of NPS gene or it is the deficiency of a separate gene linked with the gene of nail patella disorder.
