The D614G mutation was detected in at least three of 45 positive cases stemming from a restaurant owner who broke his mandatory 14-day quarantine order after returning from India, Times of India. According to a report in Bloomberg, the mutation, called the D614G was found in at least 45 cases in a cluster started from a restaurant owner. Why was the mutation named D614G? SARS-CoV-2 is the official name given to the novel coronavirus that causes COVID-19 disease. D614G is the name of one of the mutations of the virus

The D614G mutation caused a change to the coronavirus's spike protein, which is an important protein that allows the virus to enter the human body and bind to human cells D614 means the original form; the mutant form is referred to as D614G, or just G614.The coronavirus that causes COVID-19 uses its Spike protein to infect human cells. D614G refers to an amino acid mutation in this protein that has become increasingly common in SARS-CoV-2 viruses from around the world encodes a S-protein mutation, D614G, in the carboxy(C)-terminal region of the S1 domain21-23,26,30. This region of the S1 domain directly associates with S2 (Fig. 1a). This mutation with glycine at the residue 614 (G614) was previously detected to increase with an alarming speed21,22. Our own analysis of the S-protein sequences available from th The D614G mutation causes a flap on the tip of one spike to pop open, allowing the virus to infect cells more efficiently but also creating a pathway to the virus' vulnerable core. With one flap open, it's easier for antibodies — like the ones in the vaccines currently being tested — to infiltrate and disable the virus The first major COVID-19 mutation that seemed to increase contagiousness was detected early in the pandemic. Called the D614G variant, it quickly became the defining mutation of the predominant variants causing COVID-19 infections in the U.S. over the last eight months

D614G is a mutation that produces an amino acid change in the spike protein of the SARS-CoV-2 virus. This mutation appears to make SARS-CoV-2 a lot more infectious than the original virus. However, it does not appear to cause a more severe COVID-19 disease. Korber et. a. (2020) found that patients infected with this variant had higher levels of. In this scenario, D614G is the most common virus because it actually arrived in the U.S. and Europe first. With COVID-19 originating in China, founder's effects believes SARS-CoV-2 had already mutated by the time it traveled overseas. These mutations continue to alter the spike protein which attacks a patient's cells Recently Malaysia detected a ten times deadlier new COVID-19 strain known as D614G as per the country's Health Ministry. What is a mutation, Why the strain named as D614G, how much is it dangerous
