Glossary Term
Major protein component of chromatin. Highly conserved basic proteins, originally classified into classes based on the relative amounts of arginine and lysine in each protein. The various classes are now termed H1, H2A, H2B, H3, and H4. In chromatin, they are found in an octamer, containing two each of H2A, H2B, H3, and H4, complexed with DNA in nucleosomes. The histones in the octamer complex are also known as the core histones. The H1 class of histones, termed the linker histones, is loosely associated with the nucleosome.
Indicators
Produced by B-cells, human immunodeficiency virus (HIV) antibodies reacts with HIV antigens. HIV is a virus which affects white blood cells and eventually destroys the body's natural ability to fight infections.
Tests
An HIV test checks a sample of your blood, saliva (spit), or urine (pee) to see whether you are infected with HIV (human immunodeficiency virus). HIV is a virus that destroys certain cells in your immune system . These cells protect your body against diseases from germs , such as bacteria, viruses, and fungi. If you lose too many immune cells, your body will have trouble fighting off infections and other diseases.
Tests
An HIV viral load test measures the amount of HIV in a sample of your blood. HIV stands for human immunodeficiency virus. The test looks for genetic material from the virus in your blood. These tests are called molecular tests or nucleic acid amplification tests (NAAT or NAT). There are several types of NAAT tests. A PCR test is one type of NAAT that may be used to find HIV.
Tests
The determination of the number of mismatch between the study subject and his or her donor for the human leukocyte antigen, class I, group A (HLA-A).
Tests
The determination of the number of mismatch between the study subject and his or her donor for the human leukocyte antigen, class I, group B (HLA-B).
Tests
The determination of the ratio of the human leukocyte antigen DR (HLA-DR) to total cells present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The identification of the type of human leukocyte antigen, class II, antigen-D-related 52 (HLA-DR52), in a sample.
Indicators
This gene plays a role in both DNA binding and transcriptional modulation.
Tests
A homocysteine test measures the amount of homocysteine in a sample of your blood. Homocysteine is an amino acid. Amino acids are molecules that your body uses to make proteins.
Glossary Term
The process of exchange of genetic material between autonomous replicons, which depends on regions of extensive sequence homology between the participating DNA strands. This process involves double-strand breakage of one participant, resection of the break, and strand invasion, followed by formation, displacement and resolution of the Holliday junction. This process is involved in repairing broken DNA and creating combinations of genes that may be unique from the parent duplexes. Disruptions in this process can result in inviability, premature aging and predisposition to cancers and degenerative diseases.
