Alkaptonuria
|
D000474 |
[An inborn error of amino acid metabolism resulting from a defect in the enzyme HOMOGENTISATE 1,2-DIOXYGENASE, an enzyme involved in the breakdown of PHENYLALANINE and TYROSINE. It is characterized by accumulation of HOMOGENTISIC ACID in the urine, OCHRONOSIS in various tissues, and ARTHRITIS.

Alkyl and Aryl Transferases
|
D019883 |
[A somewhat heterogeneous class of enzymes that catalyze the transfer of alkyl or related groups (excluding methyl groups). EC 2.5.

|
Alkylating Agents
|
D000477 |
[Highly reactive chemicals that introduce alkyl radicals into biologically active molecules and thereby prevent their proper functioning. Many are used as antineoplastic agents, but most are very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. They have also been used as components in poison gases.

Alkylation
|
D000478 |
[The covalent bonding of an alkyl group to an organic compound. It can occur by a simple addition reaction or by substitution of another functional group.

Allantoin
|
D000481 |
[A urea hydantoin that is found in URINE and PLANTS and is used in dermatological preparations.
] |
|
Allantois
|
D000482 |
[An extra-embryonic membranous sac derived from the YOLK SAC of REPTILES; BIRDS; and MAMMALS. It lies between two other extra-embryonic membranes, the AMNION and the CHORION. The allantois serves to store urinary wastes and mediate exchange of gas and nutrients for the developing embryo.

Alleles
|
D000483 |
[Variant forms of the same gene, occupying the same locus on homologous CHROMOSOMES, and governing the variants in production of the same gene product.

Allelic Imbalance
|
D022981 |
[A situation where one member (allele) of a gene pair is lost (LOSS OF HETEROZYGOSITY) or amplified.

|
Allelopathy
|
D064089 |
[The process by which organisms release chemical compounds known as ALLELOCHEMICALS which influence the physiology, growth, survival, colonization, and reproductive activities of other species usually located nearby.

D000072223 |
[Physicians specializing in treating individuals with hypersensitivity to ALLERGENS.
] |
|
Allergoids
|
D000080384 |
[Extracts of allergens, or purified allergens that have been chemically modified to reduce their ability to induce IGE-MEDIATED HYPERSENSITIVITY (allergenicity) while increasing their ability to induce IMMUNE TOLERANCE.

|
Allergy and Immunology
|
D000486 |
[A medical specialty concerned with the hypersensitivity of the individual to foreign substances and protection from the resultant infection or disorder.

|
Allesthesia
|
D066190 |
[A neurological disorder in which a sensory stimulus, usually tactile but more rarely other sensory modalities, is misperceived in a location distant from the original stimulus.
, A condition in which a person is unable to tell which side of the body has been touched.
, A condition in which a person experiences a given stimulus, usually tactile but more rarely other sensory modalities, on the corresponding opposite side of the body from the side of the stimulation.
