contractures; short stature; small, fixed facial features; and eye abnormalities (some of which may impair vision). SJS was divided into SJS type 1 and SJS type 2 (also referred as neonatal Schwartz Jampel syndrome). SJS type 2 is now considered a distinct, more severe condition called Stuve-Wiedemann syndrome, which is caused by mutations in the LIFR gene. SJS type 1 is subdivided in type 1A and type 1B, differentiated by severity and age of onset. Type 1A, considered classic SJS, is the most commonly recognized type. People with type 1A typically develop more mild symptoms later in childhood, while people with type 1B have symptoms that are more severe and are apparent immediately after birth. SJS type 1 is caused by mutations in the HSPG2 gene. SJS type 1 is thought to be inherited in an autosomal recessive manner; however, some cases reported in the medical literature suggest an autosomal dominant inheritance pattern. Treatment for both type 1A and 1B aims to normalize muscle activity through various methods including massage and stretching, medications such as Botulinum toxin, and surgery.Schwartz Jampel syndrome (SJS) is a genetic disorder that affects bone and muscle development. Signs and symptoms may include muscle stiffness and weakness; abnormal bone development; joint
