> I read that article, and it doesn't seem like some grand revelation. Does every article of interest have to be some grand revelation? Science is all about incremental gains, with very rare leaps. Part of the why was very interesting here imo: > But genetics may also make them particularly susceptible to SARS-CoV-2, the pandemic coronavirus. They have three copies of a gene on chromosome 21, TMPRSS2, which codes for an enzyme that the virus hijacks to help it enter human cells. The TMPRSS2 enzyme cleaves the spike protein that studs the virus’ surface, launching a series of steps that allows the virus to invade the host cell. > Cells from people with DS typically express 1.6 times more TMPRSS2 than those from people without the condition This highlights why those with down syndrome are even more susceptible than those vulnerable groups you mentioned.
