Research Abstract |
The aim of this study is attempt to identify the candidate human genes those might associate with the development of high-altitude pulmonary edema (HAPE). A case-control association study was performed using 400 polymorphic microsatellite markers by PCR and sequenced byGene Scan software in HAPE susceptible subjects and HAPE resistant subjects. Nine markers showed statistically significant associations with the susceptibility to HAPE, and three markers showed significant associations with the resistance to HAPE. We also evaluated the association of HAPE with six single nucleotide polymorphisms (SNPs) in tissue inhibitor of metalloproteinase 3 (TIMP3) gene, and found that one SNP (rs130293) was significantly associated with the HAPE susceptibility (P < 0.0005). This study provides the first evidence that the development of HAPE may be determined by the interaction of multiply genes and TIMP3 may influence the risk for HAPE.
