  Schwartz-Jampel syndrome: Encyclopedia of Genetic Disorders
Abnormal bone shape and poor bone growth result in decreased total height, incorrect arm and leg postures, as well as curving of the spine (scoliosis).
These features are also due to the stiffness of the muscles that support the face and individuals with SJS appear to have a fixed facial expression.
Abnormalities in the growth and development of the bones of the spinal column (vertebrae) lead to scoliosis that usually worsens with age.

Because of the similarity to myotonic disorders, many speculate that a muscle ion-channel abnormality or a muscle enzyme defect may underlie this condition.
Some evidence exists favoring both a chloride-channel abnormality (as in generalized myotonia and myotonia congenita) and a sodium-channel abnormality (as in paramyotonia congenita, hyperkalemic periodic paralysis, or potassium-aggravated myotonia).
