Additional regions with suggestive evidence of association in both AAs and EAs include TRAK1, SLC44A4, GLI3-C7orf25, ATP8A2, and TGM3. While the biological relevance of most of these genes to sarcoidosis is still unknown, GLI3-C7orf25 and TGM3 may warrant further investigation. Here, ATP8A2 is linked to sarcoidosis.
