rs4986791, a SNP also known as Thr399Ile (and also 1196C/T) in the TLR4 gene, is often studied along with a cosegregating SNP known as Asp299Gly, rs4986790. (TLR4 encodes a receptor involved in the innate immune response.) Together, these SNPs have been reported to be associated with a wide variety of both infectious and non-infectious diseases, although there are conflicting or even contradictory results also reported in some cases. The risk allele for rs4986791 is (T).

Reported associations include [PMID 15766650]:

  • Heart disease
    • Men with the risk alleles for both SNPs are at increased risk for myocardial infarction in this study of over 2000 individuals. [PMID 15576653]
    • rs4986790(G) carriers are not at increased risk for myocardial infartions, at least in this study of ~200 individuals. [PMID 15547160]
    • rs4986790(G) carriers are less likely to have heart attacks, in this study of ~400 individuals. [PMID 14563652]
    • Individuals with the risk alleles for both SNPs have a lower incidence of carotid stenosis [PMID 12124407]
  • Allograft complications
    • A study of 300+ recipients of hematopoietic-cell transplants concluded that the adjusted hazard ratio for a recipient of developing a life-threatening invasive aspergillosis infection was 6.16x higher (CI: 1.97-19.26, p=0.002) if the donor carried these TLR4 risk alleles. This risk was statistically significant for unrelated recipients of transplants (odds ratio, 5.0, CI: 1.04-24.01, p=0.04) but did not quite meet the p=0.05 significance criteria for related recipients (odds ratio, 2.29, CI: 0.93-5.68, p=0.07).
