We found five candidate genes (Dcaf7, Dusp3, Fam134c, Psme3, and Slc4a1) within the QTL locus that were differentially expressed between susceptible and resistant mouse strains and had human orthologues with the same significant expression patterns in patients with both S. aureus BSI and E. coli BSI. This evidence concerns the gene RETREG3 and bathing suit ichthyosis.
