The invention is applicable to the technical field of
gene detection, and provides a
gene marker, a primer, a probe and a kit for predicting a child
graft versus host disease and application of the
gene marker, the primer, the probe and the kit. It is found for the first time that a combination of 12 gene markers including TPMT, UGT2B10, BHLHE22, KIAA1715, GSTA1, GSTM1, CTH, MTHFR, CYP2B6, HFE, CPS and HPSE in
peripheral blood of a child patient suffering from the
graft versus host disease and the hepatic minor
vein occlusion disease has
significant difference between
hematopoietic stem cell transplanted child patients suffering from the GVHD and
hematopoietic stem cell transplanted child patients not suffering from the GVHD, the combination can be used as one of laboratory
immunity related detection indexes for auxiliary diagnosis of the GVHD, operation is easy and feasible, and the method is suitable for clinical application. The clinical application value is very high. According to the kit for predicting the child
graft versus host disease, 17 SNP loci and one
genotype homozygous deletion are detected,
genetic typing is completed by combining a high-
throughput sequencing and
capillary electrophoresis combined method,
risk assessment can be further given according to the
typing result of a patient, and individualized susceptible gene detection is achieved.
