APOE gene is related to Alzheimer's disease, but also to Covid-19 vulnerability

 I made APOE gene statistics using the 1000 genomes data.  The APOE gene is bound to two SNPs, rs429358 and rs7412, both on the chr 19.  In the worst case both are homozygous for the allele C (e4  resulting vulnerability of 12x for late-onset Alzheimer's and 61x for early-onset disease.  If the first SNP is heterozygous and the latter CC (e3) the possbility is still >3x increased risk for Alzheimer's; 1.4x increased risk for heart disease.  Now, new studies connect these alleles also to increased risk for serious Covid disease.
