CD24/CD15 co-expression identified a correlation with high CD15 expression and low CD24 expression on WNT subgroups of medulloblastoma, with high CD24 expression and low CD15 expression correlated with SHH, Group 3 and Group 4 classifications, suggesting CD24 as a marker of non-WNT medulloblastoma. This evidence concerns the gene FUT4 and medulloblastoma.
