Abstract We report fatal cases of novel coronavirus disease (COVID-19) in three brothers in Iran. An increased susceptibility to specific pathogens has been reported for a number of genetic defects. Considering the fact that most of them who are affected by COVID-19 recover, deaths in three brothers who lived separately and had no known underlying disease suggest genetic predisposition to COVID-19 in some individuals.
“Considering the fact that most of them who are affected by COVID-19 recover, death in three brothers who lived separately is of interest. Of note, the patients’ spouses and children were not shown to be affected by COVID-19, with negative tests for SARS-CoV-2. Therefore, the three brothers who experienced fatal COVID-19 may have had a particular predisposition to infection or severe illness. It can be hypothesized that there might be a genetic predisposition to COVID-19 and/or to severe illness from COVID-19 that renders some individuals without any underlying disease at particular risk of severe or fatal illness.”
