Overview
Welcome to CGGA - the Chinese Glioma Genome Atlas! The CGGA database is a user-friendly web application for data storage and analysis to explore brain tumors datasets over 2,000 samples from Chinese cohorts. This database includes image-genomic data (274), single-cell sequencing data (73), whole-exome sequencing data (286), DNA methylation data (159), mRNA sequencing data (1,018), mRNA microarray data (301) and microRNA microarray data (198) and matched clinical data. The analyse tool allows users to browse DNA mutation profile, mRNA/microRNA expression profile and methylation profile, and to do correlation and survival analysis in specific glioma subtype.
