SMARCB1 and kidney neoplasm: Decreased expression of genes associated with neuronal development was seen in RT with SMARCB1 loss in comparison with other kidney tumours [22] and the same above mentioned processes were found to be downregulated in short survivor AT/RT patients [19], which indicates aberrant neuronal functions. DOCK4 and PTN, for example, were significantly downregulated genes in this AT/RT case.
