<\/picture><\/a><\/p>\nIn a Monday statement, the company said that preliminary results from over 750,000 participants have revealed\u00a0 clues as to why\u00a0some people experience little to no symptoms from coronavirus<\/strong>, while others become gravely ill, according to\u00a0Bloomberg<\/em><\/a>.<\/p>\n Many other groups, including 23andMe competitor Ancestry Inc., are combing the genome to help make sense of the virus.\u00a0It is known that factors such as age and underlying health conditions can determine how people fare once they\u2019ve contracted Covid-19<\/strong>. But those factors alone don\u2019t explain the wide diversity of symptoms, or why some people contract the disease and others don\u2019t. Studying the genetics of the people who are more susceptible to SARS-CoV-2 could help identify and protect those more at risk, as well as help speed treatment and drug development. –Bloomberg<\/a><\/em><\/p><\/blockquote>\n Perhaps most interesting is that\u00a0Type-O blood is also associated with a 66% reduction in the odds of developing severe malaria<\/strong>\u00a0compared to the non-O blood types, according to a\u00a02007 study<\/a>.<\/p>\n This might explain why\u00a0Hydroxychloroquine\u00a0<\/strong>and other anti-malarial drugs have shown efficacy in treating COVID-19<\/p>\n Last week,\u00a0peer reviewed research<\/a>\u00a0which analyzed the genes of more than 1,600 coronavirus patients in Italy and Spain who experienced respiratory failure suggested that\u00a0blood type may play a role in the severity of the disease<\/strong>. The found that patients with Type-A blood were linked to a 50% increase in the likelihood they would require a ventilator. The results were similar to an earlier\u00a0Chinese study<\/a>\u00a0regarding susceptibility to COVID-19.<\/p>\n “There have also been some reports of links between Covid-19, blood clotting, and cardiovascular disease<\/strong>,” said lead researcher on the 23andMe study, Adam Auton. “These reports provided some hints about which genes might be relevant.”<\/p>\n The 23andMe study, which looked at susceptibility rather than severity of illness, included 10,000 participants who told the company they had Covid-19.<\/p>\n The research found that\u00a0individuals with type O blood are between\u00a09% and 18% less likely than individuals with other blood types to have tested positive for the virus<\/u><\/strong>. However, there was little difference in susceptibility among other blood types, the study found. When the researchers adjusted the data to account for factors like age and pre-existing illnesses, as well as when it restricted the data to only those with high-probability of exposure like health-care workers, the findings were the same. –Bloomberg<\/a><\/em><\/p><\/blockquote>\n Auton say that while the results are promising, larger studies are required.<\/p>\n “It’s early days; even with these sample sizes, it might not be enough to find genetic associations,” he said. “We’re not the only group looking at this, and ultimately the scientific community may need to pool their resources to really address questions surrounding the links between genetics and Covid-19.”<\/p>\n
