Glossary Term
The global analysis of cellular proteins. Proteomics uses a combination of sophisticated techniques including two-dimensional (2D) gel electrophoresis, image analysis, mass spectrometry, amino acid sequencing, and bio-informatics to resolve comprehensively, to quantify, and to characterize proteins. The application of proteomics provides major opportunities to elucidate disease mechanisms and to identify new diagnostic markers and therapeutic targets.
Tests
A prothrombin time (PT) test measures how many seconds it takes for a clot to form in a blood sample. Since the results of this test can vary with different labs or test methods, your results may be used to create an INR (international normalized ratio). Using this ratio makes it easier for health care providers to compare and better understand results from different labs or test methods.

Research record from STAR Protoc, 2026-07-15. PMID 42455682.
Glossary Term
Nonfunctional DNA sequences that are very similar to the sequences of known genes. Many seem to have arisen as functional gene duplications that subsequently underwent mutation and loss of function. Others are structurally similar to mRNA and seem to have arisen by a reverse transcription event followed by integration into the genome. Some pseudogenes are transcribed and may play a role in regulation of its homologous gene.

Indicators
This gene is involved in tumor suppression and mutations in this gene have been associated with several cancers and cancer related diseases.
Tests
A PTEN genetic test uses a sample of your blood or other body tissue to look for changes in a gene called PTEN . Changes in your genes are also called gene variants or mutations.
Indicators
This gene plays a role in the regulation of cell signaling. It is involved in cell migration, metabolic control, mitogenic activation and gene transcription.
Glossary Term
The minimum False Discovery Rate (FDR) value required for a test to be considered significant.
Glossary Term
Programs of regular assessment of medical and nursing activities to evaluate the quality of medical care including all actions taken to ensure that standards and procedures are adhered to and that delivered products or services meet performance requirements.
Glossary Term
Set of measurements and inspections taken to verify that performance of equipment and procedures remains within specified limits.
