# Germline Data Filtering
To filter with germline data, use the “+ Add Filter” button in the Cohort Banner.
## **These filters allow for:**
* Assessing impact of ingested variants in cohorts
* Note: only non-ref variants are represented in the genomic data
* Building Cohorts based on Variants
* Develop basket studies based on your population
* Exploratory Data Analysis before GWAS
* Ask questions about co-occurrence with other mutations
## **You Can Filter By:**
* Gene Symbol or region
* Variant effect
* Variant type
* Variant ID
## Adding Germline Filters
1. Add in your dataset
2. Select "+ Add Filter"
3. Select Assays and then under Genome Sequencing, select “Genes/ Effects”
4. Then, select the genes/ impact/ variants that you want. Please note, the filtering for the Genes/ Genomic regions is by Gene Symbol or Genomic range.
