In total, 6 genes (CD160, GOLGA8B, RABGAP1L, MMP8, CRISP3, and ARG1) that were shown to be differentially expressed in PBMCs of patients with pre-eclampsia were also differentially expressed in PBMCs of PC patients, with 4 (CD160, MMP8, CRISP3, and ARG1) being differentially expressed in the same direction (1% commonality) [10]. Here, ARG1 is linked to pachyonychia congenita.
