5. Review your results on the Analysis tab. In the Details pane on the right, you canconfirm the CNV workflow and baseline used.

6. Optionally, you can download the Analysis Results and view them visually withthe cn_results.png file in the CNVBaseline folder.

Interpretation example: This plot shows log2 ratios across the genome andhighlights panel CNV IDs. The alternating blue and green color is used todistinguish between adjacent CNV IDs. The outliers are the small pink circles.The numbers at the bottom of the plot on the X axis are the chromosomes. Abovethis are the CNV ID names and the mean CN call for each CNV ID. You can seecopy number gains on chromosome 7 and chromosome 11. The MAPD numberat the top of the plot is a QC metric measuring the noisiness of the sample. AMAPD greater than 0.5 is considered to fail QC. Below the MAPD is the BAM filename. Log2 ratios of 0 are equivalent to a copy number call of 2, which is theexpected normal. If the sample was from a male, you would expect to see a copynumber of 1 for chromosome X.

Note: If using IGV Light to view Oncomine™ analyses, somatic VCIB CNV callsare listed as "passed" in the confidence column. Since Oncomine™ DNA used theVCIB CNV calling algorithm, the data fro VCIB somatic CNV calls hasConfidence Intervals, but it doesn't have the Confidence Score all other IonReporter™ CNV detection algorithms deliver. So, since that filter doesn't exist tofilter out any of the data, all of the somatic VCIB CNV calls get listed as "passed"since the Confidence filter doesn't apply to them and weeds them out.

CNV Somatic Confidence Filter

Understanding CNV Somatic Confidence Range

The somatic CNV algorithms in Ion Reporter™ Software deliver not only a ploidyestimate call, but also a pair of 90% confidence values. The 5% lower confidencebound value is the ploidy estimate where there is a 5% chance the true ploidy is belowthat value. The 95% upper confidence bound is the ploidy estimate where it is 95%certain that the true ploidy is below that value. For calling focal amplification thelower bound is important and not the upper bound.

Default filtering for the Oncomine™ Focus Assay looks for Gains whose 5%Confidence interval (5% CI) is at least a ploidy of 2 extra copies over the expectednormal ploidy value (expected ploidy is 2 for autosomes, and X in females and 1 in Xin males). The filter will look for Oncomine™ Annotated variants, and for Oncomine™

Annotated CNVs, in most cases gains of 2 + 2 (gain + expected normal)= 4. Currentlythe Oncomine™ Variant Annotator plugin annotates somatic CNVs on allchromosomes for the known copy gain genes on the Oncomine™ Focus Assay resultswhose 5% CI is >= 4.

How do I look for other gains than the default?

To create a custom somatic CNV filter, choose "CNV Somatic Confidence Range"filter, which has OR selected, and uncheck the "Enabled" checkbox for the "MinimumPloidy Loss (95% CI) user expected" filter. Double check that the the "MinimumPloidy Gain (5% CI) over expected" Enabled checkbox is checked. The new valueshould be the ploidy of gain (over expected normal) you wish to threshold on whenlooking at the 5% CI value. So if looking for gains whose 5% CI value is anything overexpected normal of autosomes (2), leave the value set at 0.0.

The default of 0.0 will find all gains whose 5% CI value is of 2 or greater. Setting thevalue to 1.0 will cause the filter look for all gains whose 5% CI value is of ploidy 3 orgreater, for example.

Please Note that the OVAT annotation will be added to known copy gain genes oneach assay's CNVs by looking at the 5%CI value of >=4.

How do I set the filter to look for gains and for losses?

This is relevant especially for the Oncomine™ Comprehensive Assay CNVs whereTumor Suppressor genes are involved and deletion may have a biological impact.

To set a custom filter to look for gains and losses using the CI values, choose the filter"CNV Somatic Confidence Range", and Enable both the "Minimum Ploidy Gain (5%CI) over expected" and the "Minimum Ploidy Loss (95% CI) under expected" filter.

We are now asking the 5% CI value and filter to threshold for Gains, and the 95% CIvalue and filter to threshold Losses.

If we set the "Minimum Ploidy Gain (5% CI) over expected greater_than" to 2.0, (2+2=4ploidy for gains, so anything 4 and above will be filtered in as a gain), and the"Minimum Ploidy Loss (95% CI) under expected to be greater_than" value to 0.0(2-0=2 ploidy for losses, so nothing exceeding expected normal of 2 will be filtered inas a loss), we can expect the following example CNV call CI data to cause the CNVdata to be filtered in or out of the results:

A gene with suspected gain with 5% CI = 4.1 and 95% CI = 10.3 will be filtered in

A gene with suspected loss with 5% CI = 0 and 95% CI = 1.0 will be filtered in

A gene with suspected gain with 5% CI = 2.2 and 95% CI = 3.6 will be filtered out (2.2is less than 4)

A gene with suspected gain with 5% CI = 2.1 And 95% CI = 5.2 Will be filtered out (2.1is less than 4)

A gene with 5% CI = 0.8 and 95% CI = 2.1 will be filtered out (0.8 is less than 4 and 2.1is greater than 2)
