The molecular origin and taxonomy of mucinous ovarian carcinoma Variant analysis. a Summary of variants across the cohort for genes mutated in > 5% of MOC; also includes copy number alterations for CDKN2A and ERBB2. BEN, benign mucinous; MBT, borderline mucinous; MOC, mucinous ovarian carcinoma; EOM, extra-ovarian metastases. b Comparison of copy number alterations and mutations with other tumor types, summarised by frequency for each. Number of cases shown below. *Higher number is for selected genes tested by Sanger sequencing/SNP arrays (see Methods); lower number from exome analysis. c Number of variants per Mb by group (ANOVA, two-sided, F = 1.55, df = 5, p = 0.18), combining exome and targeted sequencing cohorts. d Top: number of single nucleotide variants (SNV) input to signature detection from whole exome and whole genome sequencing, with each column an MOC case. Note whole genome samples truncated at 300 (asterisk). Bottom: COSMIC mutation signatures18">
