Trichorhinophalangeal Syndrome

Also known as

  • TRPS

Trichorhinophalangeal Syndrome is a genetic disorder found in one in every 100,000 people globally. This conditions causes hypermobility in all of the joints in the body; this then causes the person with TRPS to have pain in their joints. It gets it's name from how it effects hair growth (tricho), nasal structure (rhino) and the hands (phalangeal). Currently, there is little to no research on the condition due to a lack of funding.

Condition details

Definining characteristics of TRPS include abnormalities in skeleton and hypermobility in the joints. TRPS can also cause issues with learning and childhood development, weak pelvises, curvature in the fingers and smaller sinuses. It is also not common for those with TRPS to have over lapping toes on one or both of their feet. Masses can also develop over bones, due to complication with bone marrow. Effects of TRPS can vary depending on the variation of TRPS. There are three different types, with Type 3 being the most severe of them. Often those with Type 3 have more severe difficulties with their development and have learning difficulties.
