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 ...
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 ...
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]

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 most common exonic mutations of AIRE occur on exons 1, 2, 6, 8, and 10. Exons 1 and 2 encode the HSR, exon 6 encodes the SAND domain, exon 8 is in the PHD-1 domain, and exon 10 is located in the proline-rich region between the two PHD finger domains. [27] Known mutations in AIRE include Arg139X, Arg257X, and Leu323SerfsX51. [28]
As of June 2022, Omicron had about 50 mutations relative to the Wuhan-Hu-1 or B variant, [125] [126] which is more than any previous SARS-CoV-2 variant. Thirty-two of these pertained to the spike protein, which most vaccines target to neutralise the virus. [127] As of December 2021, many mutations were novel and not found in previous variants. [43]
