Supplementary Figure 2: LOH analysis on the matched normal-tumor pair from FA1b.

LOH analysis on chromosome 19 for matched normal (FA1b(N)) and tumor (FA1b(T)) DNA from sample FA1b. BAF, B-allele frequency. See the Online Methods for details on LOH analysis. LOH was seen on chromosome 19p, where SMARCA4 is located, and not on 19q (or elsewhere in the genome; Supplementary Figure 4).
