Expression of Type-A GABA receptor subunit genes in the pediatric brain cancer medulloblastoma. Shown is a heatmap across four molecular subgroups of medulloblastoma (Top row: WNT, SHH, Group 3, and Group 4) and subtypes within each subgroup (lower row), where color scaling indicates low (green) to high (red) expression. In Group 3 patient tumors (yellow), there is enhanced expression of GABRA5, which codes for the α-5 subunit. In contrast, in WNT patient tumors (blue), there is enhanced expression of a different set of GABR genes. While in SHH patient tumors (red) there is a subset of patients (purple) that share an enhanced expression of yet a different set of GABR genes. Figure adapted from Kallay, et al.
