Dolichostenomelia is a condition in which the arms and legs grow abnormally long. The abnormal growth of limbs causes the body's extremities to be narrow and long, resulting in unusual flexibility and movement. Dolichostenomelia is also referred to as congenital contractural arachnodactyly. This disease is inherited in an autosomal dominant pattern. Here are some symptoms of dolichostenomelia.
1)People with dolichostenomelia are very tall with long arms and legs.
2)They also have unusually long and slender fingers and toes.
3)Another symptom of dolichostenomelia is permanently Bent joints. permanently bent joints or contractures can cause restricted movement in knees, ankles, elbows and hips.
4)Individuals with dolichostenomelia may also have permanently flexed fingers.
5)People with dolichostenomelia can also have Underdeveloped muscles and a rounded upper back. Sometimes, the rounded upper back also has curves to the side, known as kyphoscoliosis. Kyphoscoliosis is a disease in which the thoracolumbar spine appears to have excessively deviated at multiple planes. This condition leads to deviation of normal curvature and can even include rotation of the spinal axis as well. This spine curvature can appear in a front to back and side to side curve pattern.
Other symptoms of dolichostenomelia include having permanently bent fingers and toes, also known as camptodactyly.
1) The ears may appear crumbled, and the chest may look abnormally protruding. The protruding of the chest is also known as pectus carinatum.
2) Congenital contractural arachnodactyly can cause heart issues like the enlargement of blood vessels that transport blood from the heart to other parts of the body.
3) It can also lead to leakage in valves that are responsible for controlling blood flow.
4) The abnormality may also affect the head and face, like a tiny jaw, prominent forehead, unusually wide head or narrow head.
5) Dolichostenomelia can also affect eyesight, leading to nearsightedness or myopia.
Some studies say that dolichostenomelia could be associated with aortic root dilation. This condition can lead to extra widening of the opening where the aorta connects with the heart chamber.A rare type of congenital contractural arachnodactyly also leads to abnormalities in the heart and digestive system, in addition to physical abnormality. Such individuals do not manage to live past infancy.Dolichostenomelia does not affect the life span per se, but the life expectancy varies with severity.
