Summaries for Klippel-Feil Syndrome

Genetics Home Reference : 25 Klippel-Feil syndrome is a bone disorder characterized by the abnormal joining (fusion) of two or more spinal bones in the neck (cervical vertebrae). The vertebral fusion is present from birth. Three major features result from this vertebral fusion: a short neck, the resulting appearance of a low hairline at the back of the head, and a limited range of motion in the neck. Most affected people have one or two of these characteristic features. Less than half of all individuals with Klippel-Feil syndrome have all three classic features of this condition. In people with Klippel-Feil syndrome, the fused vertebrae can limit the range of movement of the neck and back as well as lead to chronic headaches and muscle pain in the neck and back that range in severity. People with minimal bone involvement often have fewer problems compared to individuals with several vertebrae affected. The shortened neck can cause a slight difference in the size and shape of the right and left sides of the face (facial asymmetry). Trauma to the spine, such as a fall or car accident, can aggravate problems in the fused area. Fusion of the vertebrae can lead to nerve damage in the head, neck, or back. Over time, individuals with Klippel-Feil syndrome can develop a narrowing of the spinal canal (spinal stenosis) in the neck, which can compress and damage the spinal cord. Rarely, spinal nerve abnormalities may cause abnormal sensations or involuntary movements in people with Klippel-Feil syndrome. Affected individuals may develop a painful joint disorder called osteoarthritis around the areas of fused bone or experience painful involuntary tensing of the neck muscles (cervical dystonia). In addition to the fused cervical bones, people with this condition may have abnormalities in other vertebrae. Many people with Klippel-Feil syndrome have abnormal side-to-side curvature of the spine (scoliosis) due to malformation of the vertebrae; fusion of additional vertebrae below the neck may also occur. People with Klippel-Feil syndrome may have a wide variety of other features in addition to their spine abnormalities. Some people with this condition have hearing difficulties, eye abnormalities, an opening in the roof of the mouth (cleft palate), genitourinary problems such as abnormal kidneys or reproductive organs, heart abnormalities, or lung defects that can cause breathing problems. Affected individuals may have other skeletal defects including arms or legs of unequal length (limb length discrepancy), which can result in misalignment of the hips or knees. Additionally, the shoulder blades may be underdeveloped so that they sit abnormally high on the back, a condition called Sprengel deformity. Rarely, structural brain abnormalities or a type of birth defect that occurs during the development of the brain and spinal cord (neural tube defect) can occur in people with Klippel-Feil syndrome. In some cases, Klippel-Feil syndrome occurs as a feature of another disorder or syndrome, such as Wildervanck syndrome or hemifacial microsomia. In these instances, affected individuals have the signs and symptoms of both Klippel-Feil syndrome and the additional disorder.

MalaCards based summary : Klippel-Feil Syndrome, also known as klippel feil syndrome, is related to klippel-feil syndrome 2, autosomal recessive and klippel-feil syndrome 1, autosomal dominant. An important gene associated with Klippel-Feil Syndrome is GDF6 (Growth Differentiation Factor 6), and among its related pathways/superpathways are TGF-beta signaling pathway and Gene regulatory network modelling somitogenesis. The drugs tannic acid and Benzocaine have been mentioned in the context of this disorder. Affiliated tissues include bone, spinal cord and heart, and related phenotypes are embryo and growth/size/body region

Disease Ontology : 12 A physical disorder that is characterized by abnormal segmentation of the vertebra during fetal development which results in fusion located in cervical vertebra.

NIH Rare Diseases : 52 Klippel Feil syndrome (KFS) is a condition affecting the development of the bones in the spine. People with KFS are born with abnormal fusion of at least two spinal bones (vertebrae) in the neck. Common features may include a short neck, low hairline at the back of the head, and restricted movement of the upper spine. Some people with KFS have no symptoms. Others may have frequent headaches, back and neck pain, and other nerve issues. People with KFS are at risk for severe spinal injury. KFS can occur along with other types of birth defects , and sometimes KFS occurs as a feature of another disorder or syndrome. The cause of most cases of KFS is unknown, but sometimes it is caused by genetic alterations (mutations ) in one of several different genes . This condition is diagnosed based on a clinical examination, the symptoms, and imaging studies. Treatment is symptomatic and may include medications, surgery, and/or physical therapy .

NINDS : 53 Klippel-Feil Syndrome is a rare disorder characterized by the congenital fusion of two or more cervical (neck) vertebrae. It is caused by a failure in the normal segmentation or division of the cervical vertebrae during the early weeks of fetal development. The most common signs of the disorder are short neck, low hairline at the back of the head, and restricted mobility of the upper spine. The fused vertebrae can cause nerve damage and pain in the head, neck, or back. Associated abnormalities may include scoliosis (curvature of the spine), spina bifida (a birth defect of the spine), cleft palate, respiratory problems, and heart malformations. Other features may include joint pain; anomalies of the head and face, skeleton, sex organs, muscles, brain and spinal cord, arms, legs, and fingers; and difficulties hearing.  Most cases are sporadic (happen on their own) but mutations in the GDF6 (growth differentiation factor 6) or GDF3 (growth differentiation factor 3) genes can cause the disorder. These genes make proteins that are involved in bone development and segmentation of the vertebrae.

KEGG : 36 Klippel-Feil syndrome (KFS) is a rare disorder characterized by congenital fusion of two or more cervical vertebrae. Scoliosis, mirror movements, otolaryngological, kidney, ocular, cranial, limb, and/or digit anomalies are often associated. It has been reported that KFS is caused by mutations in the GDF6 or GDF3 genes in an autosomal dominant manner. KFS is also inherited in an autosomal recessive manner. Recently, involved genes (MEOX1 and MYO18B) have been identified.
