Laron syndrome is a condition that occurs when the body is unable to utilize growth hormone. It is primarily characterized by short stature. Other signs and symptoms vary but may include reduced muscle strength and endurance; hypoglycemia in infancy; delayed puberty; short limbs (arms and legs); and obesity. It is often caused by changes (mutations) in the GHR gene and is inherited in an autosomal recessive manner. Treatment is focused on improving growth and generally includes injections of insulin-like growth factor 1 (IGF-1).
What are the signs and symptoms of Laron syndrome? Laron syndrome is a rare condition in which the body is unable to use growth hormone. The primary symptom is short stature. Although affected people are generally close to average size at birth, they experience slow growth from early childhood. If left untreated, adult males with Laron syndrome typically reach a maximum height of about 4.5 feet and adult females may be just over 4 feet tall. Other signs and symptoms associated with the condition vary but may include: Reduced muscle strength and endurance Hypoglycemia in infancy Delayed puberty Small genitals Thin, fragile hair Dental abnormalities Short limbs (arms and legs) Obesity Distinctive facial features (protruding forehead, a sunken bridge of the nose, and blue sclerae) People affected by Laron syndrome appear to have a reduced risk of cancer and type 2 diabetes. The Human Phenotype Ontology provides the following list of signs and symptoms for Laron syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Abnormal facial shape 90% Aplasia/Hypoplasia involving the nose 90% Delayed eruption of teeth 90% Delayed skeletal maturation 90% High forehead 90% Microdontia 90% Reduced number of teeth 90% Truncal obesity 90% Abnormality of the elbow 50% Brachydactyly syndrome 50% Hypoglycemia 50% Hypoplasia of penis 50% Short toe 50% Skeletal muscle atrophy 50% Underdeveloped supraorbital ridges 50% Abnormality of lipid metabolism 7.5% Abnormality of the voice 7.5% Blue sclerae 7.5% Cognitive impairment 7.5% Depressed nasal ridge 7.5% Hypertrichosis 7.5% Hypohidrosis 7.5% Osteoarthritis 7.5% Prematurely aged appearance 7.5% Abnormal joint morphology - Abnormality of metabolism/homeostasis - Autosomal recessive inheritance - Delayed menarche - High pitched voice - Severe short stature - Short long bone - Small face - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
What causes Laron syndrome? Laron syndrome is caused by changes (mutations) in the GHR gene. This gene encodes growth hormone receptor, which is a protein found on the outer membrane of cells throughout the body. Growth hormone receptor is designed to recognize and bind growth hormone, which triggers cellular growth and division. When growth hormone is bound to the growth hormone receptors on liver cells, specifically, insulin-like growth factor I (another important growth-promoting hormone) is produced. Mutations in GHR impair the function of growth hormone receptors which interferes with their ability to bind growth hormone. This disrupts normal growth and development of cells and prevents the production of insulin-like growth factor I which causes the many signs and symptoms of Laron syndrome.
Is Laron syndrome inherited? Most cases of Laron syndrome are inherited in an autosomal recessive manner. This means that to be affected, a person must have a mutation in both copies of the responsible gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier. Reports exist of rare families in which Laron syndrome appears to be inherited in an autosomal dominant manner. In these cases, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. An affected person has a 50% chance with each pregnancy of passing along the altered gene to his or her child.
How is Laron syndrome diagnosed? A diagnosis of Laron syndrome is often suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis and rule out other conditions that cause similar features. This generally includes blood tests to measure the levels of certain hormones that are often abnormal in people with Laron syndrome. For example, affected people may have elevated levels of growth hormone and reduced levels of insulin-like growth factor I. Genetic testing for changes (mutations) in the GHR gene can also be used to confirm a diagnosis in some cases.
How might Laron syndrome be treated? There is currently no cure for Laron syndrome. Treatment is primarily focused on improving growth. The only specific treatment available for this condition is subcutaneous injections of insulin-like growth factor 1 (a growth-promoting hormone), often called IGF-1. IGF-1 stimulates linear growth (height) and also improves brain growth and metabolic abnormalities caused by long-term IGF-1 deficiency. It has also been shown to raise blood glucose levels, reduce cholesterol, and increase muscle growth. IGF-1 and GH levels should be closely monitored in people undergoing this treatment because overdosage of IGF-I causes a variety of health problems.

Lipodermatosclerosis refers to changes in the skin of the lower legs. It is a form of panniculitis (inflammation of the layer of fat under the skin). Signs and symptoms include pain, hardening of skin, change in skin color (redness), swelling, and a tapering of the legs above the ankles. The exact underlying cause is unknown; however, it appears to be associated with venous insufficiency and/or obesity. Treatment usually includes compression therapy.
What are the signs and symptoms of lipodermatosclerosis? Lipodermatosclerosis refers to changes in the skin of the lower legs. One or both legs may be involved. Signs and symptoms vary but may include: Pain Hardening and/or thickening of the skin Varicose veins Changes in skin color (redness) Small white scarred areas (atrophie blanche) Swelling Leg ulcers Tapering of the legs above the ankles
How might lipodermatosclerosis be treated? Lipodermatosclerosis is primarily treated with compression therapy to improve venous insufficiency. Other strategies for managing venous insufficiency include leg elevation; not sitting or standing in one place for long periods of time; regular exercise; and weight loss if overweight or obese. Some affected people may require medications to prevent blood clotting; reduce pain and inflammation; and/or increase blood flow. Depending on the severity of the condition and the response to initial treatments, vein surgery may be recommended.

Calciphylaxis is a disease in which blood vessels (veins and arteries) become blocked by a build-up of calcium in the walls of the vessels, preventing blood from flowing to the skin or internal organs.  The lack of blood flow (ischemia) damages healthy tissue and causes it to die (necrosis).  The most obvious and frequent symptom of calciphylaxis is damage to the skin, as ulcers can develop and become infected easily.  Calciphylaxis can also affect fat tissue, internal organs, and skeletal muscle, causing infections, pain, and organ failure.  These symptoms are often irreversible, and many individuals with calciphylaxis may not survive more than a few months after they are diagnosed due to infection that spreads throughout the body (sepsis), or organ failure.  The exact cause of calciphylaxis is unknown.  Treatments may include medications to reduce pain, antibiotics to treat infections, and various approaches to preventing the development or worsening of this condition.
Coffin-Siris syndrome is a genetic condition that causes variable degrees of learning disability, developmental delays, underdeveloped pinky toenails or fingernails, and distinct facial features. It can be caused by a change (mutation) in any of several genes including the ARID1A, ARID1B, SMARCA4, SMARCB1, or SMARCE1 genes. Coffin-Siris syndrome follows an autosomal dominant pattern of inheritance, however it usually occurs for the first time in a family due to a new mutation. Occupational, physical, and/or speech therapy can help affected individuals reach their full potential.
What causes Coffin-Siris syndrome? Coffin-Siris syndrome is caused by a change (mutation) in either the ARID1A, ARID1B, SMARCA4, SMARCB1, or SMARCE1 gene. Exactly how these gene mutations result in the symptoms of Coffin-Siris syndrome is not known, however it is thought that the mutations affect how genetic material is packaged in the cell. Coffin-Siris syndrome is an autosomal dominant condition; as only one gene mutation is needed to cause the syndrome. It usually occurs for the first time in a family due to a new mutation.  In some cases, no genetic mutation can be identified and the cause of Coffin-Siris syndrome in the family remains unknown.
How is Coffin-Siris syndrome diagnosed? Diagnosis of Coffin-Siris syndrome is largely based upon the presence or absence of common signs and symptoms in the individual. While formal diagnostic criteria have not been established, most individuals with a clinical diagnosis of Coffin-Siris syndrome have certain features in common. You can find detailed information on this topic at the following link to GeneReviews. http://www.ncbi.nlm.nih.gov/books/NBK131811/#coffin-siris.Diagnosis Genetic testing may also be used to diagnose or confirm cases of Coffin-Siris syndrome.
Non-A-E hepatitis, sometimes referred to as hepatitis X, is a disease of the liver that is diagnosed when there is swelling of the liver (hepatitis) but examination and testing does not identify a cause.  Symptoms of non-A-E hepatitis may include feeling tired or unwell (malaise), nausea, vomiting, pain in the abdomen, and fever.  Non-A-E hepatitis usually goes away on its own, but it can become a chronic condition in a small proportion (12%) of affected individuals.  The cause of non-A-E hepatitis is currently unknown.
