Langer-Giedion syndrome is a very rare genetic disorder caused by a deletion of chromosomal material. It is named after the two doctors who undertook the main research into the condition in the 1960s. Diagnosis is usually made at birth or in early childhood.
The features associated with this condition include mild to moderate learning difficulties, short stature, unique facial features, small head and skeletal abnormalities including bony growths projecting from the surfaces of bones. Typically individuals with Langer-Giedion syndrome have fine scalp hair, ears that may be large or prominent, broad eyebrows, deep-set eyes, a bulbous nose, long narrow upper lip, and missing teeth.
The syndrome occurs when a small piece of chromosome 8’s long arm, which contains a number of genes is missing. The loss of these genes is responsible for some of the overall characteristics of Langer-Giedion syndrome. This disorder is also called trichorhinophalangeal syndrome, or LGCR (for Langer-Giedion Chromosome Region).
While no genetic syndrome is capable of being cured, treatments are available for some symptoms. External fixators have been used for limbic and facial reconstructions.
