# Somatic Data Filtering

To filter with somatic data, use the “+ Add Filter” button in the Cohort Banner. 

## **These filters allow for:**

* Assessing impact of ingested somatic variants in cohorts
* Building Cohorts based on Somatic Variants
* Exploratory Data Analysis

## **You Can Filter By:**

* Gene Symbol or Genomic Range
* Variant effect
* Variant type
* HGVS Notation 
* Variant IDs

## Adding Somatic Filters

1. Add in your dataset
2. Select "+ Add Filter"
