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 cancer syndrome or family cancer syndrome is a genetic disorder in which inherited genetic mutations in one or more genes predisposes the affected individuals to the development of cancers and may also cause the early onset of these cancers. Although cancer syndromes exhibit an increased risk of cancer, the risk varies.
Indel (insertion-deletion) is a molecular biology term for an insertion or deletion of bases in the genome of an organism. Indels ≥ 50 bases in length are classified as structural variants. [1] [2] In coding regions of the genome, unless the length of an indel is a multiple of 3, it will produce a frameshift mutation.
DROP The detection of RNA Outliers Pipeline (DROP) is an integrative workflow to detect aberrant expression, aberrant splicing, and mono-allelic expression from raw sequencing files. [ 61 ] EBSeq is a Bioconductor package for identifying genes and isoforms differentially expressed (DE) across two or more biological conditions in an RNA-seq ...
Hereditary cancer syndromes underlie 5 to 10% of all cancers and there are over 50 identifiable hereditary forms of cancer. [5] Scientific understanding of cancer susceptibility syndromes is actively expanding: additional syndromes are being found, [6] the underlying biology is becoming clearer, and genetic testing is improving detection, treatment, and prevention of cancer syndromes.

The CLiP technique integrates multiple distinctive genomic features of a cancer of interest findings within a machine-learning framework for cancer detection. For example, studies have shown that the majority of somatic mutations found in cell-free DNA (cfDNA) are not tumor derived, but instead reflect clonal hematopoeisis (also known as CHIP).
