Supplementary Figure 1: LOH analysis in SCCOHT tumors with SMARCA4 mutations.

LOH analysis was performed using bcbio-nextgen 0.7.7a-e91123c to map reads with BWA 0.7.5a to GRCh37 and freebayes v0.9.10-11 for joint variant calling restricted to chr. 19: 10,667,750–11,554,548. The heat map shows SNPs with a call rate of 0.2. No evidence of LOH was observed.
