Well this is kind of fascinating! Certain gene alleles are particularly associated with those COVID patients who lost their taste and smell.
Not that there's anything to do with this information, but I always find it interesting to know a bit more rather than less -- in this case about why some people got these symptoms and others didn't.
"Researchers at the 23andMe COVID-19 Team, who help search for genetic links associated with the severity of COVID-19, found that the genes UGT2A1 and UGT2A2 may be associated with the loss of smell in those infected with SARS-CoV-2."
"The study results showed an association with the UGT2A1 and UGT2A2 genes and the emergence of anosmia in COVID-19 positive people. These genes are included in the family of uridine diphosphate glycosyltransferases, are expressed in the olfactory epithelium, and work as odorant metabolizing enzymes. Also, these genes play a critical role in the physiology of olfaction."
