Both children and adults can be affected by Larsen syndrome. It is a condition that is present from birth and can have lifelong implications. Individuals with Larsen syndrome may require ongoing medical care and support to manage their symptoms and lead as healthy a life as possible.

Types of Larsen syndrome

Larsen syndrome has two types: type 1 and type 2. Type 1 is the classic form, and it is characterized by joint dislocations or deformities, like in the knees and elbows. People with this type may also have unusual facial features and differences in their fingers and toes. Type 2 is a more severe form, where babies are born with life-threatening complications like severe respiratory problems and heart issues. They may also have more severe joint problems and have intellectual disabilities. Both types of Larsen syndrome are caused by changes in the genetic instructions that cells follow to make certain proteins.

Diagnostic of Larsen syndrome

Larsen syndrome is diagnosed through a series of medical tests and evaluations by doctors. These tests may include physical examinations to check for physical abnormalities such as joint deformities, facial features, and spine curvature. Doctors may also order imaging tests like X-rays, MRIs, or CT scans to get a better look at the skeletal structure and any abnormalities present. Genetic testing may also be conducted to identify specific genetic mutations associated with Larsen syndrome. By combining the information gathered from these tests, doctors can make a diagnosis of Larsen syndrome.
