About the year 1994 Dr Alan Roses at Duke announced that a gene called ApoE4 made human carriers much more likely to come down with Alzhiemer’s disease, and within a week scientists nearby at UNC-CH announced that gene version ApoE2 was linked to higher cholesterol levels. There are also versions ApoE1 and ApoE3.
Now British researchers report that carriers of the ApoE4 gene get worse cases of COVID-19 while carriers of ApoE3 get milder cases
