Purpose
CD163 is a member of the scavenger receptor cysteine-rich family (SRCR) is exclusively expressed on cells of the monocyte lineage.CD163 acts to amplify inflammation and serves as a critical mediator of inflammatory response in the context of sepsis. This study was designed to investigate whether CD163 genomic variations were associated with the prognosis of sepsis. We sequenced 30 sepsis patients with CD163 gene of seventeen exons by PCR sequencing. When analyzing the results of sequencing, we found five gene polymorphisms located in exon-2,exon-5 and exon-11, respectively. Compare with the NCBI dbSNP and Hapmap database, one polymorphisms located in exon-2 is non-synonymous variation rs3210140, two polymorphisms located in exon-5 are synonymous variations rs4883264 and rs4883263, the last two located in exon-11 are synonymous variations rs61729512 and rs150018775 . Five common polymorphisms (rs2234237,rs2234246) within the CD163 gene were detected in 200 patients with severe sepsis and in 200 healthy control subjects. This study was explored that whether or not polymorphisms detected within the CD163 gene may play a major role in the predisposition to prognosis of sepsis in a Chinese Han cohort.
