Do Your Genes Predispose You to COVID-19?
Individual differences in genetic makeup may explain our susceptibility to the new coronavirus and the severity of the disease it causes

Two other studies have recently come out, posted on the other thread, one of which looks at it in terms of "continental" groups, which shows the highest susceptibility to severity of result in East Asians, followed by Africans, followed by Europeans.
Another looks at it in terms of Europe and finds a higher susceptibility in Southern Europe versus Northern Europe.
This all mirrors previously discovered higher susceptibilities to HIV infection, which shares some coding with CoV-2, and perhaps also to plague.
Of course, this is all preliminary, and it would only be one factor, but if it turns out they're right, it would go some way to explaining differing outcomes in Europe, and also what is happening with black and Hispanic Americans, and what happened with the original SARS outbreak in Asia. At the slightest, earliest hint of a new virus in China East Asian countries rush to put on masks and isolate carriers. They've been down this road before.
