Indicators
A steroid hormone synthesized by the adrenal glands and the gonads from either 17-alpha-hydroxyprogesterone or dehydroepiandrosterone and is a precursor of testosterone.
Indicators
Human ANPEP wild-type allele is located within 15q25-q26 and is approximately 30 kb in length. This allele, which encodes aminopeptidase N protein, is involved in the modulation of peptide hydrolysis and human infection by cytomegalovirus and coronavirus.
Indicators
An autoantibody that recognizes histidyl-tRNA synthetase, cytoplasmic protein.
Indicators
An antinuclear antibody directed against a 47 kDa RNA-binding protein in the nucleus. They can be associated with Sjogren syndrome and system lupus erythematosus. Maternal anti-La antibody positivity can be associated with neonatal lupus.
Indicators
An antinuclear antibody directed against U1 snRNP, that is strongly associated with mixed connective tissue disease and commonly detected in lupus.
Indicators
An antinuclear antibody directed against 52 or 60 kDa RNA-binding proteins in the nucleus. They can be associated with multiple autoimmune disorders, primarily Sjogren syndrome and system lupus erythematosus. Maternal anti-Ro antibody positivity can be associated with neonatal lupus.
Glossary Term
A type of protein made by B lymphocytes in response to a foreign substance (antigen). Each antibody only binds to a specific antigen, helping to destroy the antigen directly or by assisting white blood cells to destroy the antigen.
Glossary Term
Any substance, generally a protein, that stimulates the immune system and elicits an immune response. Recognition by the immune system elicits either a T-lymphocyte response, recognizing processed antigens, or a B-lymphocyte response, producing antibodies that bind to unprocessed antigens.
Tests
The determination of the amount of antiphospholipid antibodies present in a sample.
Tests
The determination of the ratio of apolipoprotein A compared to apolipoprotein B present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the amount of apolipoprotein CIII present in a sample.
Indicators
This gene plays a role in the transcriptional activation of androgen responsive genes.
