There could be a genetic susceptibility or genetic resistance, but that could be said for just about anything when discussing on a chromosomal level. It is just not practical because unless it is tied to a major genetic trait, like one of the 4 major blood antigen groups, it is very difficult to study under these circumstances. Given the desire to do so, someone could probably find genetic markers for susceptibility to COVID 19 in 2 or 3 years, but at that point, its too late. The virus will either be gone or mutated.
While it is possible that people of Italian descent can share genetic markers that might make them more susceptible, it is far more likely due to 3 factors.
High median age
High rate of smoking
Lack of medical resources
That last one is a little bit loaded, because if any illness gets bad enough, even the best equipped countries can lack medical resources.
