WebFor example, HIV isolates carrying the K103N mutations can have degrees of resistance to efavirenz [Sustiva]. In some viruses, the K103N mutation can produce a 10,000-fold increase in the IC50, whereas in other viruses we see an IC50 fold change of less than 100. It all seems to depend on all of the polymorphisms present in this region of ... WebMutation. A permanent change in the genetic material of a cell or microorganism. Some mutations can be transmitted when the cell or microorganism replicates. Some HIV mutations cause the virus to become resistant to certain antiretroviral (ARV) drugs.
