[Progress of research on association between schistosomiasis and single nucleotide polymorphisms]

Single nucleotide polymorphisms (SNP) has been regarded as a new genetic marker due to its rich dynamics and relatively stable heredity. SNP can express the relationship between genes and diseases to seek disease-linked genes particularly. A number of domestic and international studies have demonstrated that the formation of schistosomiasis egg granuloma is closely linked to HLA-Ⅱ related antigen. By detecting alleles loci of HLA-Ⅱ gene, researchers can identify the gene or haplotype that is associated with the susceptibility and progression of schistosomiasis. The detected candidate genes can serve useful therapeutic and preventative purposes by providing new technical methods to defeat schistosomiasis. In-depth study on SNP is beneficial to evaluate schistosomiasis inclination clinically, as well as to promote early diagnosis and preventive treatment.
