The name of the mutation, del 69-70, or 69-70 del, or other similar notations, refers to the deletion of amino acid at position 69 to 70. The mutation is found in the Alpha variant, and could lead to "spike gene target failure" and result in false negative result in PCR virus test. [270]
The test matches RNA in three locations, and stopped working for the spike gene due to the HV 69–70 deletion—a deletion of the amino acids histidine and valine in positions 69 and 70, respectively [262] —in the spike protein of lineage B.1.1.7. This made preliminary identification easier because it could be better suspected which cases ...
A subject of the Tuskegee syphilis experiment has his blood drawn, c. 1953.. Numerous experiments which were performed on human test subjects in the United States in the past are now considered to have been unethical, because they were performed without the knowledge or informed consent of the test subjects.

Li–Fraumeni syndrome (LFS) is a rare, autosomal dominant, hereditary disorder [1] that predisposes carriers to cancer development.It was named after two American physicians, Frederick Pei Li and Joseph F. Fraumeni Jr., who first recognized the syndrome after reviewing the medical records and death certificates of childhood rhabdomyosarcoma patients. [2]

In late October, Eldiara Doucette found out she only had five days left with her arm. The 22-year-old's synovial sarcoma − a rare cancer that affects soft tissue − had returned. Her hospital's ...
It has mutations in the gene encoding the SARS-CoV-2 spike protein [6] causing the substitutions T478K, P681R and L452R, [7] [8] which are known to affect transmissibility of the virus as well as whether it can be neutralised by antibodies for previously circulating variants of the COVID-19 virus.

The gene encoding CD69 is located in the NK gene complex on chromosome 6 and chromosome 12 in mice and humans respectively. [7] Activation signaling pathways in lymphocytes, NK cells, dendritic cells and other cell types upregulate transcription factors, such as NF-κB, ERG-1 (erythroblast transformation-specific related gene-1), and AP-1 (activator protein), in order to promote the ...
