Familial Cold Autoinflamatory Syndrome (FCAS)
Cold urticaria (essentially meaning cold hives) is a disorder in large red welts called hives (''urticaria'') form on the skin after exposure to a cold stimulus. The hives are usually itchy and often the hands and feet will become itchy and swollen as well. Hives vary in size from about in diameter to as big as about or larger. This disorder, or perhaps two disorders with the same clinical manifestations, can be inherited (''familial cold urticaria'') or acquired (''primary acquired cold urticaria''). The acquired form is most likely to begin between ages 18 and 25, although it can occur as early as 5 years old in some cases. Life-threatening risks include suffocation resulting from swollen tissue (Pharynx, pharyngeal angioedema) induced by cold foods or beverages, drowning after shock from swimming in cold water, and anaphylactic shock. Types Cold urticaria may be divided into the following types: Primary cold contact urticaria Primary cold contact urticaria is a cutaneous c ...

Dermatology
Dermatology is the branch of medicine dealing with the skin.''Random House Webster's Unabridged Dictionary.'' Random House, Inc. 2001. Page 537. . It is a speciality with both medical and surgical aspects. A dermatologist is a specialist medical doctor who manages diseases related to skin, hair, nails, and some cosmetic problems. Etymology Attested in English in 1819, the word "dermatology" derives from the Greek δέρματος (''dermatos''), genitive of δέρμα (''derma''), "skin" (itself from δέρω ''dero'', "to flay") and -λογία '' -logia''. Neo-Latin ''dermatologia'' was coined in 1630, an anatomical term with various French and German uses attested from the 1730s. History In 1708, the first great school of dermatology became a reality at the famous Hôpital Saint-Louis in Paris, and the first textbooks (Willan's, 1798–1808) and atlases ( Alibert's, 1806–1816) appeared in print around the same time.Freedberg, et al. (2003). ''Fitzpatrick's Dermatology in ...

Arthralgia
Arthralgia (from Greek ''arthro-'', joint + ''-algos'', pain) literally means ''joint pain''. Specifically, arthralgia is a symptom of injury, infection, illness (in particular arthritis), or an allergic reaction to medication. According to MeSH, the term "arthralgia" should only be used when the condition is non-inflammatory, and the term "arthritis" should be used when the condition is inflammatory. Causes The causes of ''arthralgia'' are varied and range, from a joints perspective, from degenerative and destructive processes such as osteoarthritis and sports injuries to inflammation of tissues surrounding the joints, such as bursitis. These might be triggered by other things, such as infections or vaccinations. Diagnosis Diagnosis involves interviewing the patient and performing physical exams. When attempting to establish the cause of the arthralgia, the emphasis is on the interview. The patient is asked questions intended to narrow the number of potential causes. Given th ...

The Lancet
''The Lancet'' is a weekly peer-reviewed general medical journal and one of the oldest of its kind. It is also the world's highest-impact academic journal. It was founded in England in 1823. The journal publishes original research articles, review articles ("seminars" and "reviews"), editorials, book reviews, correspondence, as well as news features and case reports. ''The Lancet'' has been owned by Elsevier since 1991, and its editor-in-chief since 1995 has been Richard Horton. The journal has editorial offices in London, New York City, and Beijing. History ''The Lancet'' was founded in 1823 by Thomas Wakley, an English surgeon who named it after the surgical instrument called a lancet (scalpel). Members of the Wakley family retained editorship of the journal until 1908. In 1921, ''The Lancet'' was acquired by Hodder & Stoughton. Elsevier acquired ''The Lancet'' from Hodder & Stoughton in 1991. Impact According to the ''Journal Citation Reports'', the journal has a 202 ...

Protein Data Bank
The Protein Data Bank (PDB) is a database for the three-dimensional structural data of large biological molecules, such as proteins and nucleic acids. The data, typically obtained by X-ray crystallography, NMR spectroscopy, or, increasingly, cryo-electron microscopy, and submitted by biologists and biochemists from around the world, are freely accessible on the Internet via the websites of its member organisations (PDBe, PDBj, RCSB, and BMRB). The PDB is overseen by an organization called the Worldwide Protein Data Bank, wwPDB. The PDB is a key in areas of structural biology, such as structural genomics. Most major scientific journals and some funding agencies now require scientists to submit their structure data to the PDB. Many other databases use protein structures deposited in the PDB. For example, SCOP and CATH classify protein structures, while PDBsum provides a graphic overview of PDB entries using information from other sources, such as Gene ontology. History Two force ...

Human Genome Organisation
The Human Genome Organisation (HUGO) is a non-profit organization founded in 1988. HUGO represents an international coordinating scientific body in response to initiatives such as the Human Genome Project. HUGO has four active committees, including the HUGO Gene Nomenclature Committee (HGNC), and the HUGO Committee on Ethics, Law and Society (CELS). History HUGO was established at the first meeting on genome mapping and sequencing at Cold Spring Harbor in 1988. The idea of starting the organization stemmed from South African biologist Sydney Brenner, who is best known for his significant contributions to work on the genetic code and other areas of molecular biology, as well as winning the 2002 Nobel Prize in Physiology or Medicine. A Founding Council was elected at the meeting with a total of 42 scientists from 17 different countries, with Victor A. McKusick serving as founding President. In 2016, HUGO was located at the EWHA Womans University in Seoul, South Korea. In 2020, the H ...

HGNC
The HUGO Gene Nomenclature Committee (HGNC) is a committee of the Human Genome Organisation (HUGO) that sets the standards for human gene nomenclature. The HGNC approves a ''unique'' and ''meaningful'' name for every known human gene, based on a query of experts. In addition to the name, which is usually 1 to 10 words long, the HGNC also assigns a symbol (a short group of characters) to every gene. As with an SI symbol, a gene symbol is like an abbreviation but is more than that, being a second unique name that can stand on its own just as much as substitute for the longer name. It may not necessarily "stand for" the initials of the name, although many gene symbols do reflect that origin. Purpose Especially gene abbreviations/symbols but also full gene names are often not specific for a single gene. A marked example is CAP which can refer to any of 6 different genes (BRD4'', CAP1'', HACD1'', LNPEP'', SERPINB6'', and SORBS1''). The HGNC short gene names, or gene symbols, unlike ...

Gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gen ...

Cryopyrin-associated Periodic Syndrome
Cryopyrin-associated periodic syndrome (CAPS) is a group of rare, heterogeneous autoinflammatory disease characterized by Interleukin 1 beta, interleukin 1β-mediated systemic inflammation and clinical symptoms involving skin, joints, central nervous system, and eyes. It encompasses a spectrum of three clinically overlapping autoinflammatory syndromes including familial cold autoinflammatory syndrome (FCAS, formerly termed familial cold-induced urticaria), the Muckle–Wells syndrome (MWS), and neonatal-onset multisystem inflammatory disease (NOMID, also called chronic infantile neurologic cutaneous and articular syndrome or CINCA) that were originally thought to be distinct entities, but in fact share a single genetic mutation and pathogenic pathway, and keratoendotheliitis fugax hereditaria in which the autoinflammatory symptoms affect only the anterior segment of the eye. Signs and symptoms The syndromes within CAPS overlap clinically, and patients may have features of more than ...

National Institutes Of Health
The National Institutes of Health, commonly referred to as NIH (with each letter pronounced individually), is the primary agency of the United States government responsible for biomedical and public health research. It was founded in the late 1880s and is now part of the United States Department of Health and Human Services. The majority of NIH facilities are located in Bethesda, Maryland, and other nearby suburbs of the Washington metropolitan area, with other primary facilities in the Research Triangle Park in North Carolina and smaller satellite facilities located around the United States. The NIH conducts its own scientific research through the NIH Intramural Research Program (IRP) and provides major biomedical research funding to non-NIH research facilities through its Extramural Research Program. , the IRP had 1,200 principal investigators and more than 4,000 postdoctoral fellows in basic, translational, and clinical research, being the largest biomedical research instit ...

NOMID
Neonatal-onset multisystem inflammatory disease is a rare genetic periodic fever syndrome which causes uncontrolled inflammation in multiple parts of the body starting in the newborn period. Symptoms include skin rashes, severe arthritis, and chronic meningitis leading to neurologic damage. It is one of the cryopyrin-associated periodic syndromes. NOMID can result from a mutation in the ''CIAS1'' gene (also known as ''NLRP3'' gene), which helps control inflammation. Mutations in this gene also cause familial cold urticaria and Muckle–Wells syndrome. NOMID has been successfully treated with the drug anakinra. This syndrome is also known as the Prieur–Griscelli syndrome as it was first described by these authors in 1981.Prieur AM, Griscelli C (1981) Arthropathy with rash, chronic meningitis, eye lesions, and mental retardation. J. Pediat 99:79-83 Signs and symptoms The age of onset is almost always before 3 months of age. Many infants are born preterm (1/3 cases) and dysmature ...

Muckle–Wells Syndrome
Muckle–Wells syndrome (MWS) is a rare autosomal dominant disease which causes sensorineural deafness and recurrent hives, and can lead to amyloidosis. Individuals with MWS often have episodic fever, chills, and joint pain. As a result, MWS is considered a type of periodic fever syndrome. MWS is caused by a defect in the CIAS1 gene which creates the protein cryopyrin. MWS is closely related to two other syndromes, familial cold urticaria and neonatal onset multisystem inflammatory disease—in fact, all three are related to mutations in the same gene and subsumed under the term cryopyrin-associated periodic syndromes (CAPS). Sign and symptoms * Sensorineural deafness * Recurrent urticaria (hives) * Fevers * Chills * Arthralgia (painful joints) Causes MWS occurs when a mutation in the ''CIAS1'' gene, encoding for NLRP3, leads to increased activity of the protein cryopyrin. This protein is partly responsible for the body's response to damage or infection. During these states, a ...

CIAS1
NLR family pyrin domain containing 3 (NLRP3) (previously known as NACHT, LRR and PYD domains-containing protein 3 ALP3and cryopyrin), is a protein that in humans is encoded by the ''NLRP3'' gene located on the long arm of chromosome 1. NLRP3 is expressed predominantly in macrophages and as a component of the inflammasome, detects products of damaged cells such as extracellular ATP and crystalline uric acid. Activated NLRP3 in turn triggers an immune response. Mutations in the NLRP3 gene are associated with a number of organ specific autoimmune diseases. Nomenclature NACHT, LRR, and PYD are respectively acronyms for: * NACHT – NAIP (neuronal apoptosis inhibitor protein), C2TA heterokaryon_incompatibility)_and_TP1_(telomerase-associated_protein_1) *_ MHC,_HET-E_(Podospora_anserina#Heterokaryon_incompatibility">heterokaryon_incompatibility)_and_TP1_(telomerase-associated_protein_1) *_Leucine-rich_repeat">LRR_–_"leucine-rich_repeat"__and_is_synonymous_with_NLR,_for_''_o ...
