Polymorphisms in TREX1 and susceptibility to HIV-1 infection

TREX-1 is a restriction factor against HIV-1. The coding sequence of TREX1 gene was analysed in HIV+ subjects searching for genetic variations possibly associated with the susceptibility to HIV infection. The single nucleotide polymorphism rs3135945 was significantly associated with HIV infection, emphasizing the involvement of TREX-1 in the anti-HIV response.
