PHOENIX, Ariz. Dec. 15, 2020 The Translational Genomics Research Institute (TGen), an affiliate of City of Hope, has identified a specific genetic target that could help explain the tremendous variation in how sick those infected with COVID-19 become.
The study results, recently published in the journal
mSphere, describe a molecule made from DNA miR1307 as a potential dimmer switch that may influence the severity of the disease; why some infected with SARS-CoV-2, the virus that causes COVID-19, have mild or even no symptoms, while others become seriously ill or die.
Led by Nicholas Schork, Ph.D., a Distinguished Professor and Director of TGen s Quantitative Medicine and Systems Biology Division, researchers identified miR1307 by comparing the genetic elements of SARS-Cov-2 with seven other human coronaviruses, some of which merely cause common colds. In addition, they examined the genomes of coronavirus strains known to infect bats, pigs, pangolins, ferrets, civ
