Abstract

The present invention relates to novel Human Immunodeficiency Virus 1 (HIV-1) variants that are resistant against protease inhibitors including the high genetic barrier protease inhibitor R0033-4649 and show mutations not in the protease itself but in the viral Gag protein (Matrix and Capsid) and the viral cleavage sites thus establishing a novel resistance mechanism. The invention further relates to diagnostic assays for determining the presence in a sample of the HIV variant.
