Abstract:
Toll-like receptor 3 (TLR3) may be associated with T helper 1 immune response. This study aimed to investigate the role of a functional TLR3 single nucleotide polymorphism (SNP) in sarcoidosis. We genotyped 220 Japanese patients with sarcoidosis and 140 controls for TLR3 SNP rs3775291 to analyze its association with susceptibility to sarcoidosis and assessed its relationship to clinical features in 172 patients over 2 years. The TLR3 rs3775291 genotype was not significantly associated with disease susceptibility. However, patients with cardiac sarcoidosis (CS) significantly more frequently had the TT genotype (p < 0.01) or the T allele (p < 0.05) than those patients without CS. We conclude that TLR3 SNP rs3775291 may affect cardiac involvement in Japanese patients with sarcoidosis.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
