Genetics May Predispose Susceptibility to COVID

child, mother and grandmother

It is generally accepted that COVID-19 (coronavirus disease 2019) is caused by an infection with the virus SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). The virus enters human cells via a protein coding gene known as ACE2 (angiotensin converting enzyme 2). It is also largely accepted that COVID can affect different people in different ways, ranging from asymptomatic infection to severe disease, which can include respiratory failure and death. Some studies note, “risk factors for severe COVID-19 include male sex, older age, ethnicity, obesity and cardiovascular and respiratory diseases, among others.”1 2 3 4

Additionally, genetic factors have been shown to play a role in a person’s susceptibility to infection with SARS-CoV-2 and to developing severe symptoms of COVID.

Studies Suggest Genetic Factors Determine Reactions to COVID

Numerous studies have been undertaken to try and understand how host genetic factors can predispose someone to COVID. One study, for example, published in the journal Biochemistry and Biophysics Reports in December 2020 investigated how different “coding variants” of ACE2 among certain populations decreased or increased the SARS-CoV-2/ACE2 “electrostatic attention” or “binding energy.”2 5 6 

The authors stated:

Here, we combined ACE2 coding variants’ analysis in different populations and computational chemistry calculations to probe the effects on SARS-CoV-2/ACE2 interaction. ACE2-K26R; which is most frequent in Ashkenazi Jewish population decreased the SARS-CoV-2/ACE2 electrostatic attraction. On the contrary, ACE2-I468V, R219C, K341R, D206G, G211R increased the electrostatic attraction; ordered by binding strength from weakest to strongest. The aforementioned variants are most frequent in East Asian, South Asian, African and African American, European, European and South Asian populations, respectively.6

In another study published in the journal BMC Medicine in July 2020, researchers investigated genetic susceptibility to COVID by examining DNA polymorphisms (two or more variant forms) in ACE2 and the gene TMPRSS2 (transmembrane protease, serine 2). They identified 63 “potentially deleterious” variants in ACE2 and 68 “deleterious” variants in TMPRSS2, and they found that the “distribution of deleterious variants in ACE2” differs among nine populations. The researchers wrote:

Specifically, 39% (24/61) and 54% (33/61) of deleterious variants in ACE2 occur in African/African-American (AFR) and Non-Finnish European (EUR) populations, respectively Prevalence of deleterious variants among Latino/Admixed American (AMR), East Asian (EAS), Finnish (FIN), and South Asian (SAS) populations is 2–10%, while Amish (AI) and Ashkenazi Jewish (ASJ) populations do not appear to carry such variants in ACE2 coding regions.7

There are many other similar studies that indicate that genetic factors within different geographic and ethnic groups can play a role in the susceptibility of these populations to SARS-CoV-2 infection and the manifestation of COVID symptoms. This may explain why COVID has affected certain people disproportionately.8 9 10

Biology Can Also Determine Reactions to Other Diseases, Toxins and Vaccination

This realization, however, should come as no great surprise. After all, we are all different genetically, epigenetically. Consequently, each of us can react differently to diseases, environmental toxins and medical interventions such as vaccination.

“Each one of us is born with different genes and a unique microbiome influenced by epigenetics that affects how we respond to diseases and pharmaceutical products like vaccines,” says Barbara Loe Fisher, co-founder and president of the National Vaccine Information Center.11

One of the best examples of how genetic variation can determine the susceptibility of a race or ethnic group to disease is sickle-cell disease, which is more common in African and Mediterranean populations than in northern European populations. The opposite is the case for the genetic disorder cystic fibrosis and the condition known as hemochromatosis (iron overload).12

According to the Susan G. Komen Foundation, the chances of a woman developing breast cancer can be determined by her ethnic background. For example, white and black women are more likely to get breast cancer than Asian/Pacific Islander or Hispanic women.13

We are biologically diverse, and that can be a strength or a weakness, depending on the threats we face. This has perhaps never been more true than with the COVID pandemic and the COVID shots.

Many people, regardless of their limited exposure to the SARS-CoV-2 virus or vaccination status, came down with COVID. On the other hand, there were many people who, despite heavy exposure to SARS-CoV-2, never got COVID. “There are numerous examples of couples in which one partner got seriously ill, and the spouse was taking care of them yet did not get infected,” said András Spaan, MD, PhD, a clinical microbiologist at the St. Giles Laboratory of Human Genetics of Infectious Diseases at New York’s Rockefeller University.14

The same can be said for the COVID shots. Approximately 81 percent of the people in the United States received at least one dose of the available COVID shots. Some 70 percent of the people in the U.S. were “fully vaccinated,” meaning at least two doses or equivalent. Many of those people experienced no noticeable short-term harm from the shots. However, many of them did and were left with Long COVID Vaccination Syndrome (LCVS) or died.15 16 17

  1. Variations in the shot formulations could also be the reason that some had bad reactions. There was a site that tracked the batch numbers and the incidents of adverse events. Seems it varied by batch. Some shots were more toxic than others. Also another factor is the starting health point of the shot recipient. How well could you detox the poison just injected into your arm? No need to be looking at genetics to see why people get sick or die when injected with poison.

  2. There was never any covid “virus”. Everything goes away when that is realized. There may be a poison, a toxin, or just people getting sick from the yearly things, like having an immune system that isn’t functioning, and needs to detox, or constant exposure to EMF and microwave frequencies which are everywhere. Or a lab made parasite. But to keep referring to Covid as a virus, just keeps the fear alive which is how they trapped the world to begin with.

    1. Terry: true, true and so true! thank you for your comment – saving this old one her typing skills for another day 🙂 – – there is now such a large group of researchers, doctors and others in various scientific fields (yes, even that strange one: virology) to give us more than adequate proof (the foundation the scientific method of correct controls/Koch’s posulates, i.e., true isolation, etc.) that this has not been done but a deceit all along (can we say, “Rockefeller”?). Well, there, I did use up much typing skills, anyway!

  3. “It is also largely accepted that COVID can affect different people in different ways, ranging from asymptomatic infection…” My take is that the so-called asymptomatic infections are the result of false positives from the inappropriately applied PCR test.

  4. I believe including Covid shots in this article is a mistake. The fact is, proven, that there were inconsistencies in the manufacture of these shots and different batches produced different results, at least partially because there were different “ingredients” in the batches.

  5. Good gene testing can reveal if someone has impaired genes – SNPs contributed by EACH parent that impedes good gene expression by 70% in the offspring. Impaired genes for detoxification or low glutathione status could predispose someone to immune system dysregulation that increases susceptibility to viral, bacterial, and/or fungal infections and possibly forewarn of a likely bad reaction to vaccines.

  6. Part of the article is very confusing with all those technical words. Marco didn’t explain it well, sorry. 🤷‍♀️🤦🏼‍♀️

    Not everyone can understand medical or scientific words. Hope it makes sense.

  7. How do you know there as no virus? I chose to not get the jab, but would like to know what your sources are.
