# Genetic Data Resources outside FinnGen

The FinnGen Analysis team incorporates into [PheWeb](https://results.finngen.fi) genetic overlaps with published GWAS data in [GWAS Catalog](https://www.ebi.ac.uk/gwas/) and [ClinVar](https://www.ncbi.nlm.nih.gov/clinvar/). However, there are a number of other places you might use to explore your data.

### **How to view allele frequencies - gnomAD**

For viewing worldwide allele frequencies and looking at measures of severity of a particular variant, [gnomAD](https://gnomad.broadinstitute.org/) is the best option. There are different reference genomes available there, but if you search using the variant ID that begins “*rs*” then you will not have to consider which reference sequence you have (FinnGen genotypes are referenced to the [GRCh 38](https://www.ncbi.nlm.nih.gov/assembly/GCF_000001405.26/) of the human genome; [gnomAD](https://gnomad.broadinstitute.org) v3.1.1).

### Where is the gene expressed in - GTEx

To understand which organ systems your gene is expressed in and if the variant you are interested in causes and gene-specific expression regulation you can find that in [GTEx](https://gtexportal.org/home/). In GTEx you can explore expression quantitative trait loci (eQTLs, i.e. genetic variants that explain variance in mRNA expression levels). If you are interested in protein-level expression you can visit [The Human Protein Atlas](https://www.proteinatlas.org/).

### Public resources - OpenTargets

For a complete view of the public resources about the genetics of a variant or gene, you can visit the [OpenTargets ](https://genetics.opentargets.org/)(be careful to select "*OpenTargets **Genetics*****"** as your search engine term, as there have another site which is not as useful).

### Publications - PubMed

Of course, when discovering a new association and looking for what biology is known, it is always good to search [PubMed](https://pubmed.ncbi.nlm.nih.gov/). Keep in mind that FinnGen uses the canonical reference name for the gene but genes often have many aliases, especially in older literature. [Gene Cards](https://www.genecards.org/) is one easy place you can look up all the aliases for a gene. Often Googling your variant/gene or searching it on Twitter can also provide recent and interesting results.
