About dolichostenomelia

What is dolichostenomelia?

The term dolichostenomelia comes from the Greek words 'dolichos,"steno,' and'melia,' which mean long, narrow, and of the limbs, respectively. It is a human condition in which a person's limbs are unusually long and narrow. It mostly affects connective tissue. It is a common symptom of several hereditary diseases, including Marfan syndrome and homocystinuria.

Marfan Syndrome is a rare autosomal dominant disorder that primarily affects the body's connective tissue. It is caused by a mutation in FBN1, a gene responsible for the production of fibrillin, which results in abnormal connective tissues. Dolichostenomelia, like scoliosis and abnormally flexible hand and foot joints, is a notable skeletal system symptom. The eyes, bones, and lungs are the most commonly affected body organs. In severe cases, the heart and aorta are affected because of tricuspid valve collapse and aortic aneurysm.

Homocystinuria (HCU) is an autosomal recessive trait that causes metabolic problems. The cause is a lack of cystathionine beta-synthase, also known as methionine synthase. It can also be caused by a lack of vitamins like pyridoxine, cyanocobalamin, and folic acid. Dolichostenomelia is a prominent musculoskeletal symptom of this disease. This disease is distinguished by an accumulation of homocysteine, an amino acid, in the serum and an increase in the amount of homocysteine released from the urine. Dolichostenomelia was mentioned in one of the episodes of the crime drama television series Rizzoli & Isles. Maura Isles, the main character, went on a date with a man who had dolichostenomelia, concluding that the man must have Marfan Syndrome.

What are the symptoms for dolichostenomelia?

Dolichostenomelia is a condition characterised by abnormally long arms and legs. Because of abnormal limb growth, the body's extremities are narrow and long, resulting in unusual flexibility and movement. Congenital contractural arachnodactyly is another name for dolichostenomelia. This disease has an autosomal dominant inheritance pattern. Here are some dolichostenomelia symptoms.

1)Dolichostenomelia patients are very tall, with long arms and legs.

2)They have unusually long and slender fingers and toes as well.

3)Permanently bent joints are another sign of dolichostenomelia. Contractures or permanently bent joints can limit movement in the knees, ankles, elbows, and hips.

4)People who have dolichostenomelia may have permanently flexed fingers.

5)Dolichostenomelia patients may also have Underdeveloped muscles and a rounded upper back. Kyphoscoliosis is a condition in which the rounded upper back has side curves. Kyphoscoliosis is a condition in which the thoracolumbar spine appears to have deviated excessively in multiple planes. This condition causes a deviation in normal curvature and can even result in rotation of the spinal axis. This spine curvature can occur in both a front-to-back and side-to-side pattern.

Dolichostenomelia is also characterised by permanently bent fingers and toes, a condition known as camptodactyly. 

1) The ears may appear crumbled, and the chest may protrude abnormally. Pectus carinatum is another name for chest protrusion.

2) Congenital contractural arachnodactyly can lead to heart problems such as enlargement of blood vessels that carry blood from the heart to other parts of the body.

3) It can also cause leakage in valves that control blood flow.

4) The abnormality may also affect the head and face, such as a small jaw, a prominent forehead, an unusually wide or narrow head.

5) Dolichostenomelia can also impair vision, causing nearsightedness or myopia.

According to some research, dolichostenomelia may be linked to aortic root dilation. This condition can result in an enlargement of the opening where the aorta connects to the heart chamber. In addition to physical abnormalities, a rare type of congenital contractural arachnodactyly causes heart and digestive system abnormalities. Such individuals do not survive childhood. Dolichostenomelia does not affect life expectancy per se, but it does vary with severity.

What are the causes for dolichostenomelia?

Dolichostenomelia, also known as congenital contractual arachnodactyly, is a condition in which limbs such as the legs and arms grow abnormally long. Dolichostenomelia also causes slender and narrow fingers and toes, as well as other symptoms that can affect the heart and digestive system. Dolichostenomelia can be caused by the following factors: Changes or mutations in the fibrillin-2 (FBN2) gene can cause dolichostenomelia. The fibrillin-2 (FBN2) gene encodes instructions for the production of fibrillin-1, an essential protein. This protein travels from cells to the extracellular matrix. This matrix is a complex lattice of many other proteins and molecules that aids in the formation of spaces between cells.

A mutation in this gene can prevent the production of the aforementioned protein. If fibrillin-1 is not present, it prevents the formation of microfibrils, which results in abnormal tissues. These mutations have an impact on the body's connective tissues. Connective tissue problems can also affect the growth and development of bones in the toes and fingers, as well as the arms and legs, resulting in typically long limbs. Because of their nearly identical medical symptoms, Marfan Syndrome and dolichostenomelia were thought to be the same disorder for many years. Recent studies, however, show that the mutations occur in different genes, proving that dolichostenomelia is not the same as Marfan syndrome.

Even though dolichostenomelia is a distinct disorder, its similarities to Marfan syndrome made determining the correct incidence of dolichostenomelia difficult. Another thing to keep in mind is that Dolichostenomelia is not always caused by underlying health problems. People are frequently born with slender fingers and toes. The true cause of dolichostenomelia is being researched, and other research has found overlapping symptoms with Lorys Dietz syndrome.

What are the treatments for dolichostenomelia?

Dolichostenomelia is the abnormal growth of the human body's long and narrow extremities, such as the arms and legs. It also affects the joints of people who have unusual movement and flexibility in some cases. Although no permanent cure for dolichostenomelia has been discovered, medical science has advanced sufficiently to allow patients to live longer and healthier lives. People died at a young age in the early days as a result of this. People with dolichostenomelia can now live normal lives like everyone else.

Here are a few options for treating this symptom: Physical therapy is extremely beneficial in treating joint abnormalities. With controlled movements, the therapy makes the joints more mobile. Physiotherapy can also help with muscle hypoplasia, a type of dolichostenomelia. Typically, the calf muscles are affected. Physical therapy also helps with this condition and relieves the patient's pain. In severe cases, surgery is the best option for immediate relief. Extensive outdoor activities and strenuous exercise should be avoided. Playing light games is encouraged.

Scoliosis, also known as kyphosis, is a chronic and progressive symptom of dolichostenomelia. Scoliosis is best treated with bracing and surgical treatment. The advice of spine specialists should be taken seriously. Surgery is recommended for protruding or sunken breastbones and sternums. An orthopedist, a doctor who specialises in bone casting, bracing, and surgery, should be consulted for advice and regular check-ups. Many more symptoms and developments could occur. They should be treated as soon as the first symptoms appear. Any delay can have serious consequences. Legs should be checked on a regular basis. Physicians and physiotherapists can track the growth and development of any asymptomatic symptom. It should be part of the patient's routine. There are numerous support groups for people who have dolichostenomelia. Patients should join such groups for moral and emotional support, and they will learn how to live with this or any other genetic disorder much more easily.

What are the risk factors for dolichostenomelia?

Dolischoma is a human syndrome in which the limbs are generally longer than normal, i.e. the arm span is greater than the individual's height. As a result, the body may appear slightly disproportionate. It is a common feature of a group of hereditary connective tissue disorders known collectively as the Marfan syndrome. The following are the risk factors for dolichostenomelia:

1) An increased infection rate during or after any surgery.

2) Postoperative neurological deficits and abnormalities caused by abnormal limb length.

3) Increased risk of pseudarthrosis as a result of failed spinal fusion attempts.

4) Blood loss may be greater than normal following any injury, trauma, or surgery.

5) Cardiovascular issues: Because of disproportionate limbs and body size, muscles in patients with dolichostenomelia or Marfan's syndrome can have problems with the heart and circulatory system, such as: Weakened aortic walls, aortic dilation, cystic medial degeneration of valves, aortic aneurysm, and aortic dissection.

6) Eye and vision problems include: early onset of cataracts and glaucoma, risk of retinal tears, and lens dislocation.

7) Dural tears are common after spinal surgeries and can be severe in patients who already have Marfan's syndrome with dolichostenomelia.

8) Orthopedic complications arise as a result of abnormal skeletal structure: Dolichostenomelia is caused by long bone overgrowth and is typically seen in people with abnormally tall height combined with a thin frame that appears disproportionate. According to studies, athletes with tall and lean frames who participate in sports like basketball and volleyball are frequently patients suffering from Marfan's syndrome with cardiovascular complications like aortic enlargement. In the case of dolichostenomelia, the human musculoskeletal system suffers greatly, and corrective surgeries combined with regular medical checkups of the cardiovascular, nervous, and ocular systems are required to keep the risk factors at bay.

Is there a cure/medications for dolichostenomelia?

A hereditary or uncommon condition like dolichostenomelia is difficult to diagnose. Marfan syndrome (dolichostenomelia) is a condition that affects the body's connective tissues, which are a group of tissues that help to maintain the structure of the body and support internal organs and other tissues. Because the symptoms of Marfan syndrome vary so much from person to person, it is difficult to diagnose. Because Marfan syndrome symptoms do not always appear during childhood, it is possible that it will not be diagnosed until adolescence. In 99 percent of cases, a genetic test can confirm a diagnosis of Marfan syndrome.

However, because the gene can mutate in over 3,000 different ways, it is an expensive process. In most cases, a thorough physical examination and a thorough examination of a person's medical and family history are used to diagnose Marfan syndrome. Testing Materials. The Genetic Testing Registry (GTR) contains information on the genetic tests that are available for this disorder. The GTR's target audiences are health care providers and researchers. Patients and consumers who have specific questions about a genetic test should consult a doctor or a genetics expert.


Collaboration in contracting Physical therapy improves joint mobility and alleviates muscular hypoplasia symptoms (usually in the calf muscles). In extreme cases, surgery may be required. Because kyphosis/scoliosis progresses, bracing and/or surgical treatment are frequently required. It is recommended that you see an orthopedist. If additional symptoms appear, they should be addressed as they appear. Schedule regular doctor appointments to monitor the progression and development of symptoms.
