Genetic subgroup of small ruminant lentiviruses that infects sheep homozygous for TMEM154 frameshift deletion mutation A4Δ53
Résumé
Small ruminant lentivirus (SRLV) infections of sheep are influenced by genetics on both the host and pathogen sides. Genetic variation in the ovine transmembrane 154 (TMEM154) gene associates with infection susceptibility, and distinct SRLV genetic subgroups infect sheep in association with their TMEM154 diplotypes. In this study, a novel SRLV subgroup was identified that naturally infected sheep with various TMEM154 diplotypes, including those homozygous for a rare frameshift mutation (A4 delta53), which is predicted to abolish TMEM154 protein function. Thus, these SRLVs may infect sheep that lack functional TMEM154, and may not be restricted by TMEM154 diplotypes in establishing infections.
