Maternal-Infant Haplotypes and Tissue Rejection Pathways in Placental Villitis Examination

Overview

About this study

The purpose of this study is to identify genetic and molecular signatures of Villitis of Unknown Etiology (VUE) related to disease severity and poor pregnancy/fetal outcomes. In our first aim, we will evaluate the associations between maternal-infant HLA alleles, eplets and VUE. In our second aim, we will determine whether activation and upregulation of organ rejection genes/pathways is altered in VUE with poor outcomes.
