Supplementary Figure 3: SMARCA4 results from cases with and without SMARCA4 mutations.

(a) Immunostaining results from familial cases. Chromatograms are shown in Figure 1 where available. (b) Immunostaining results and chromatograms for cases where mutations were found in non-familial cases and cases of unknown family history with SCCOHT, classic type. (c) Immunohistochemistry results and chromatograms of mutations from non-familial cases and cases of unknown family history with SCCOHT, large cell type. (d) Immunohistochemistry results and chromatograms of mutations for the group with unknown family history where the diagnoses were less certain and for non-SCCOHT cases. (e) Immunohistochemistry results for SCCOHT mimics. Note that SMARCA4 immunostaining is retained in all cases.
