The skeletal structures of individuals who have this disorder may have pronounced deformities. As reported by several medical doctors, the following features are commonly found in people who with<unk> : Bones and joints AP radiograph showing a hypoplastic<unk>  in NPS AP radiograph of the right iliac crest showing a bony exostosis or posterior iliac horn, which is pathognomonic of NPS *<unk> r involvement is present in approximately 90% of patients; however,<unk> r aplasia occurs in only 20%. * In instances in which the<unk> e are smaller or luxated, the knees may be unstable. * The elbows may have limited motion (e.g., limited pronation, supination, extension). * Subluxation of the radial head may occur. * Arthrodysplasia of the elbows is reported in approximately 90% of patients. * General hyperextension of the joints can be present. * Exostoses arising from the posterior aspect of the iliac bones ("iliac horns") are present in as many as 80% of patients; this finding is considered pathognomonic for the syndrome. * Other reported bone changes include scoliosis, scapular hypoplasia, and the presence of cervical ribs.

Side affects may include frequent headaches, blurred vision, or total vision loss. This occurs gradually over time and symptoms may not be evident in children. Kidney issues may arise such as deposition of protein in the urine and nephritis. Proteinuria is usually the first sign of kidney involvement and either rapidly or years after suffering from asymptomatic deposition of protein in the urine, kidney failure occurs in around 5% of NPS patients. Hypothyroidism, irritable bowel syndrome, attention deficit hyperactivity disorder (ADHD), and thin tooth enamel are associated with NPS, but whether these are related or simply coincidences are unclear.
