Placental gene expression profiling for the identification of subtypes of human fetal growth restriction

Fetal growth restriction (FGR) is a heterogeneous disorder of pregnancy associated with pathologically low fetal and neonatal weights. We hypothesized that FGR consists of multiple placental subtypes, similar to what we have observed in preeclampsia. To address this hypothesis, we assembled a fetal growth-focused human placental microarray data set (N=97) consisting of 20 new normotensive suspected FGR samples (below), in addition to term controls (N=26) and hypertensive suspected FGR samples (N=51) from GSE75010.
