Main name of condition: Stratton-Parker syndrome Other names or spellings for Stratton-Parker syndrome: Short stature [wormian bones - dextrocardia] . Stratton-Parker syndrome: A very rare syndrome characterized by short stature, heart positioned on the wrong side of the chest (dextrocardia) and a bone development anomaly.

SHORT syndrome

SHORT syndrome is a medical condition in which affected individuals have multiple birth defects in different organ systems. SHORT is an acronym for short stature, hyperextensibility of joints and/or inguinal hernia, ocular depression, rieger anomaly and teething delay. Short stature refers to any person who is significantly below the average height for a person of the same age and sex -- specifically, the shortest 3 - 5% of the population. The term often refers to children or adolescents who are significantly below the average height of their peers.

Shprintzen Golberg craniosynostosis

Shprintzen-Goldberg craniosynostosis syndrome (SGS) is a disorder of the connective tissue, featuring craniosynostosis and marfanoid body type. SGS, also known as marfanoid craniosynostosis syndrome, is one of a group of disorders characterized by craniosynostosis and marfanoid body type. It is a condition that involves craniofacial, skeletal, and other abnormalities. SGS is caused by genetic mutations (changes affecting the structure and function of the gene) in a gene that contributes to the formation of connective tissue.

Shprintzen omphalocele syndrome

Shprintzen omphalocele syndrome: A rare syndrome characterized mainly by abnormal development of the pharynx and larynx which can result in a narrowed airway. Protrusion of intestines through the belly button also occurs. The voice is high pitched and spinal curvature and learning problems are other common symptoms.

Shwachman-Diamond syndrome

Shwachman–Diamond syndrome (SDS or Shwachman–Bodian–Diamond syndrome) is a rare congenital disorder characterized by exocrine pancreatic insufficiency, bone marrow dysfunction, skeletal abnormalities, and short stature. After cystic fibrosis (CF), it is the second most common cause of exocrine pancreatic insufficiency in children.

Shwartzman phenomenon

Shwartzman phenomenon: A body reaction to certain toxins which results in the formation of a blood clot which can causes affected tissue to die. The symptoms can vary depending on what part of the body is exposed to the endotoxin. The reaction may be localized or systemic.

Sialadenitis

Sialadenitis (bacterial infection of a salivary gland) Sialadenitis is a painful infection that usually is caused by staphylococcus, streptococcus, Haemophilus influenzae or anaerobic bacteria. Although it is very common among elderly adults with salivary gland stones, sialadenitis also can occur in infants during the first few weeks of life. Many things increase the risk of this condition, including dehydration, recent surgery, prematurity, malnutrition, eating disorders, chronic illness, cancer, medications (antihistamines, diuretics, psychiatric medications, beta-blockers, barbiturates), Sjgren's syndrome and certain occupations (trumpet playing, glass blowing). Without proper treatment, sialadenitis can develop into a severe infection, especially in people who are debilitated or elderly.

Sialidosis type 1 and 3

Sialidosis type 1 and 3: A rare inherited biochemical disorder involving the deficiency of an enzyme (alpha-N-acetylneuraminidase) which results in the harmful accumulation of certain chemicals (sialyloligosaccharides and sialylglycopeptides) in various body tissues.

Sialuria- French type

Sialuria, French type: A rare disorder characterized by the excretion of large amounts of sialic acid in the urine due to a metabolic error.

Sickle cell anemia

Sickle cell anemia is a disease in which the body produces abnormally shaped red blood cells that have a crescent or sickle shape. These cells do not last as long as normal, round, red blood cells, which leads to anemia (low number of red blood cells). The sickle cells also get stuck in blood vessels, blocking blood flow. Signs and symptoms of sickle cell disease usually begin in early childhood and may include anemia, repeated infections, and periodic episodes of pain (called crises). This condition is caused by mutations in the HBB gene and is inherited in an autosomal recessive pattern. Treatment typically focuses on controlling symptoms and may include pain medicines during crises; hydroxyurea to reduce the number of pain episodes; antibiotics and vaccines to prevent bacterial infections; and blood transfusions

Siderius X-linked mental retardation syndrome

Siderius type X-linked mental retardation syndrome: A rare inherited form of mental retardation involving a defect on chromosome Xp11.2. The symptoms are evident in males but females may be carriers.

Sideroblastic anemia- autosomal

Sideroblastic anemia, autosomal: An inherited form of anemia where an enzyme deficiency prevents red blood cells from using iron properly. The red blood cells become overloaded with iron which impairs the blood's ability to carry oxygen.

Siderosis

Siderosis: Abnormal deposits of iron in body tissues. Symptoms will depend on which tissues the iron is deposited in.

Siegler Brewer Carey syndrome

Siegler-Brewer-Carey syndrome: A very rare syndrome characterized mainly by cataracts, ear infections, poor absorption by the intestines, respiratory infections and failure to thrive.

Silicosiderosis

Silicosiderosis: A lung disorder caused by breathing in dust containing iron and silica.

Silicosis

Alternative Names: Acute silicosis; Chronic silicosis; Accelerated silicosis; Progressive massive fibrosis; Conglomerate silicosis. Silicosis is a respiratory disease caused by inhaling silica dust.

Sillence syndrome

Sillence syndrome: An extremely rare genetic disorder primarily involving digit abnormalities, scoliosis and club feet.

Silver-Russell dwarfism

Silver-Russell dwarfism, also called Silver-Russell syndrome (SRS) or Russell-Silver syndrome (RSS) is a growth disorder occurring in approximately 1/75000 births. In the United States it is usually referred to as Russel-Silver Syndrome, and Silver-Russell Syndrome elsewhere. It is one of 200 types of dwarfism and one of five types of primordial dwarfism and is one of the few forms that is considered treatable. Its exact cause is unknown, but present research points toward a genetic component, possibly following maternal genes. There is no statistical significance of the syndrome occurring in males or

Silvery hair syndrome

Chédiak-Higashi like syndrome, (also known as Griscelli syndrome, Silvery hair syndrome, or Albinism partial immunodeficiency) is a similar rare childhood autosomal recessive disorder that causes hypopigmentation of the skin and the hair, and can cause a fatal hemophagocytic syndrome, for which the only cure is bone-marrow transplantation. Chédiak-Higashi syndrome is a rare childhood autosomal recessive disorder that affects multiple systems of the body, which arises from a mutation in the lysosomal trafficking regulator gene, LYST. It is a disease with impaired bacteriolysis due to failure of phagolysosome formation. As a result of disordered intracellular trafficking there is impaired lysosome degranulation with phagosomes, so phagocytosed bacteria are not destroyed by the lysosome's enzymes. In addition secretion of lytic secretory granules by cytotoxic T cells is also affected. The disease is characterised by large lysosome vesicles in phagocytes, which thus have poor bactericidal function, leading susceptibility to infections, abnormalities in nuclear structure of leukocytes, anaemia, and hepatomegaly.

Simian B virus infection

Simian B virus infection: A type of herpesvirus which occurs in monkeys but can be transmitted to humans through bites or through contact with infected monkey tissue as in a laboratory situation. The virus infects the brain (encephalitis) and the surrounding membrane (meningitis).

Simosa cranio facial syndrome

Simosa craniofacial syndrome: A rare disorder characterized by a range of facial anomalies including a high forehead, long face, flat face and a small mouth.

Simpson-Golabi-Behmel syndrome

Simpson-Golabi-Behmel syndrome (SGBS) is a rare X-linked recessive inherited condition. It causes general overgrowth in height and weight. Individuals with SGBS also have characteristic facial features in childhood which tend to become less obvious in adulthood. SGBS is also known as Simpson dysmorphia syndrome (SDYS), bulldog syndrome, Golabi-Rosen syndrome, and dysplasia gigantism syndrome X-linked (DGSX). SGBS is a rare X-linked recessive inherited condition. Individuals with this condition have increased height and weight for their age; a broad, stocky appearance; a large protruding jaw; a short, broad nose; incomplete closure of the roof of the mouth (cleft palate); and broad, short hands and fingers. Individuals with SGBS are usually taller than average. The characteristic features usually become less apparent in adulthood. There are at least two genes for SGBS. Both genes are located on the X chromosome.
