# Proteomics

A summary of the proteomic data available so far in FinnGen is provided below. For additional information, please check the corresponding subpages (e.g., Expansion area 5 and FinnGen 3).

For information about the individual/sample selection criteria, please check the file in FinnGen Teams/Task Forces/Shared/General with the name ["FinnGen\_proteomics\_summary\_table.xlsx"](https://helsinkifi.sharepoint.com/:x:/s/FinnGen150/IQArIK0q7dtnSKumgXgo2oqBARTe-gaAmpgk9NI8N4En1Dw?e=XsSdJl).
