Germline and Somatic Variants
This histogram shows the frequency distribution of allele ratio for total called germline and somatic variants. Listed below the figure is the combined total of called germline and somatic variants. The value is reported in the statistic.txt file as Variant count (Germline + somatic). For more information, see View the tumor mutational burden statistics.
Only Somatic Variants
This histogram shows the frequency distribution of allele ratio for only somatic mutations as determined by the selected TMB filter chain. Listed below the figure are:
The number of variants determined to be nonsynonymous (detrimental) and synonymous (non-detrimental) as annotated by Ion Reporter™ Software. Values are reported by different Ion Reporter™ annotation types in the statistic.txt file.

Substitution Type and Context of Somatic Mutations
Somatic mutations can be divided into 6 base substitution classes (that is, C>A, C>G, C>T, T>A, T>C, T>G) based on their substitution type. After incorporating information on the bases immediately 5′ and 3′ to each mutated base, 96 possible mutation types are in this classification. These 96 mutation types are represented on the x‑axis, and variant frequency for mutation type on the y‑axis. Bars for each substitution class are grouped and displayed with different color.

Signature Pattern of Somatic Mutations
A pie chart dividing somatic mutations in groups consistent with specific mechanisms.
In the pie chart, a small fraction of multiple signature types can be observed in the sample. However, significant dominance of a single signature pattern often correlates to the respective tumor type. For example, 56.7% of the variants detected (sum of blue, green, and yellow) are an observed UV damage signature in this sample.

High C>A is consistent with smoking damage.(Orange)
