“Some people are asymptomatic, they feel no symptoms when they get the disease, while others end up in the hospital,” said Cyril Moukarzel, co-founder and CEO of LifeDNA. “Some of it is obviously correlated to age and their lifestyle and environment, but a big portion of it could also be attributed to DNA and genetic variations in DNA — and that’s what we’ll be studying.”
Cyril Moukarzel of the Honolulu genomic company LifeDNA said a person’s genetics may impact their reaction to the new coronavirus.

The project will focus on a specific gene called the ACE2 gene, which scientists say could be the gateway that allows the coronavirus to invade human cells. The gene may have an impact on how vulnerable a person’s lungs are to the virus once it enters the body.
“When it attacks the body, the virus likes to go after the lungs and essentially what it does is it binds to certain receptors on your lungs and those receptors are created by that particular gene,” Moukarzel explained. “Certain people might not have as many of those receptors as others, and that’s due to a particular genetic variation in the DNA.”
Ethnicity may play a role in determining why some people and global populations appear to be hit harder by the disease. The recovery rate for infected patients in China and South Korea, for example, seems to be higher than those of European countries, according to realtime data available online.
“It is possible that Asians have more resistance to the virus,” said Moukarzel, who said he suspects that genetic variations will differ by race.
Another factor could be the efficiency of governments in their efforts to tamp down the virus.
Maarit Tiirikainen, a molecular epidemiologist at the University of Hawaii Manoa, is leading an initiative to collect positive testing samples from COVID-19 patients in Hawaii so that she and a team of researchers can analyze the DNA for variations of a gene that could be the entry point for coronavirus in the human body.

Moukarzel and his research partner Maarit Tiirikainen, an epidemiologist at UH Manoa, plan to study the gene with the goal of uncovering whether certain ethnicities within Hawaii’s population are more susceptible to coronavirus and its more severe symptoms.
The researchers plan to partner with a Hawaii laboratory to obtain positive COVID-19 patient samples, on which they will perform a DNA analysis. According to Moukarzel, the research team is still working out the lab partnership.
When the study is complete, the researchers expect that the findings will identify the most vulnerable people and populations to coronaviruses — information that could be invaluable ahead of a future outbreak.

Civil Beat readership has more than doubled in the past nine months. That’s incredible growth for which we’re so grateful.
But for a small nonprofit newsroom that provides free content with no paywall, readership growth alone can’t sustain our journalism. The truth is that less than 1% of our monthly readers are financial supporters.
To remain a viable business model for local news, we need a higher percentage of readers-turned-donors.
