Insights

Certain CTLA-4 gene polymorphisms are linked to infection risk in organ transplant recipients. This meta-analysis identified specific variants associated with increased infection susceptibility, highlighting potential genetic factors in post-transplant outcomes.

Area of Science:

  • Immunogenetics
  • Transplantation Science
  • Infectious Disease Epidemiology

Background:

  • Organ transplantation success is influenced by various factors, including genetic predispositions.
  • The role of specific gene polymorphisms, particularly within the CTLA-4 gene, in post-transplant infection risk remains unclear.

Conclusions:

  • Specific CTLA-4 gene polymorphisms, namely CTLA4+49 [A/G-231775] and CTLA4 [rs5742909TT], are significantly associated with infection risk following organ transplantation.
  • Further research into gene-gene and gene-diet interactions is recommended to elucidate the complex relationship between genetic factors and post-transplant infections.
