Although the number of MRT samples analyzed in our work is too low to allow for final conclusions about CLDN6 staining in this entity, discrepancy on the frequency of positive samples within intracranial rhabdoid tumors (AT/RTs) has been reported as varying from 100% [16] to 29% [17] and 39% [15]. The gene discussed is CLDN6; the disease is rhabdoid tumor.
