Application of LRRC4 gene promoter zone methylation detection to glioma diagnosis and detection system

The invention discloses an application of the LRRC4 gene promoter methylation detection to the glioma diagnosis and a detecting system thereof. The brain tissue specificity expressive gene LRRC4 is the glioma specificity methylate alienation gene, thereby indicating that the LRRC4 gene promoter methylation detection can be applied to the early period diagnosis of the glioma and the LRRC4 gene promoter methylation detecting system can be prepared by comprising a DNA bisulfite modification kit and an LRRC4 promoter methylation specificity PCR augmentation kit. The detecting system detects the specificity of the plasma LRRC4 promoter methylation state up to 92 percent, has high sensitivity, and can detect the plasma LRRC4 promoter methylation state of people quantificationally, thereby diagnosing the glioma of the patient rapidly without wound in the early time.
