Rare Mutations in CCDC7 Contribute to Early-Onset Preeclampsia by Inhibiting Trophoblast Migration and Invasion.

ABSTRACT: Rare gene variants have been found to play a role in complex disorders. Preeclampsia, and especially early-onset preeclampsia, has a strong genetic link. However, the role of rare variants in the offspring of mothers with preeclampsia remains unclear. In this study, whole-exome sequencing (WES) was used to identify rare pathogenic variants in two families with early-onset preeclampsia. Two heterozygous rare variants in CCDC7, c.625C>T (p.R209C) and c.1015C>T (p.R339X), were detected in two families and were cosegregated in the offspring of preeclamptic pregnancies. We examined the spatiotemporal expression pattern of CCDC7 in human placental villi and the effects of CCDC7 on migration and invasion of trophoblast cells JEG-3.
