However, with regard to the fdr-values, only 2 of all these genes remained differentially expressed as depicted in Figure S1, i.e., decreased expression of calcium transport protein 1 (CAT1) and increased expression of SMAD specific E3 ubiquitin protein ligase 1 (SMURF1), both in the sarcoidosis group. The gene discussed is TRPV6; the disease is sarcoidosis.
