विवरण

Jacobsen syndrome is a condition caused by a loss (deletion) of genetic material from chromosome 11. Because this deletion most commonly occurs at the end (terminus) of the long (q) arm of chromosome 11, Jacobsen syndrome is also known as 11q terminal deletion disorder.

The signs and symptoms of Jacobsen syndrome vary considerably. Most affected individuals experience delayed development of certain skills, including speech and motor skills (such as sitting, standing, and walking). Most also have cognitive impairment and learning difficulties. Behavioural problems have been reported, including compulsive behaviour (such as shredding paper), a short attention span, and easy distractibility. Many people with Jacobsen syndrome have been diagnosed with attention-deficit/hyperactivity disorder (ADHD). Jacobsen syndrome is also associated with an increased likelihood of autism spectrum disorder, which is characterised by impaired communication and socialization skills.

Jacobsen syndrome is also characterised by distinctive facial features. These include small and low-set ears, widely set eyes (hypertelorism) with droopy eyelids (ptosis), skin folds covering the inner corner of the eyes (epicanthal folds), a broad nasal bridge, downturned corners of the mouth, a thin upper lip, and a small lower jaw. Affected individuals often have a large head size (macrocephaly) and a skull abnormality called trigonocephaly, which gives the forehead a pointed appearance.

More than 90 percent of people with Jacobsen syndrome have a bleeding disorder called Paris-Trousseau syndrome. This condition causes a lifelong risk of abnormal bleeding and easy bruising. Paris-Trousseau syndrome is a disorder of platelets, which are blood cells that are necessary for blood clotting.

Other features of Jacobsen syndrome can include heart defects, such as underdevelopment of the left side of the heart (hypoplastic left heart syndrome); feeding difficulties in infancy; short stature; frequent ear and sinus infections; and skeletal abnormalities. The disorder can also affect the digestive system, kidneys, and genitalia.

The life expectancy of people with Jacobsen syndrome is unknown, although affected individuals have lived into adulthood. Complex heart defects are a leading cause of death in people with Jacobsen syndrome. Bleeding episodes and infections can also be life-threatening in people with Jacobsen syndrome.
