Noncoding RNA-regulated gain-of-function of STOX2 in Finnish pre-eclamptic families.

The familial forms of early onset pre-eclampsia and related syndromes (HELLP) present with hypertension and proteinuria in the mother and growth restriction of the fetus. Genetically, these clinically similar entities are caused by different founder-dependent, placentally-expressed paralogous genes. All susceptibility genes (STOX1, lincHELLP, INO80B) identified so far are master control genes that regulate an essential trophoblast differentiation pathway, but act at different entry points.

Susceptibility allele-specific loss of miR-1324-mediated silencing of the INO80B chromatin-assembly complex gene in pre-eclampsia.

In humans, the elucidation of the genetics underlying multifactorial diseases such as pre-eclampsia remains complex. Given the current day availability of genome-wide linkage- and expression data pools, we applied pathway-guided genome-wide meta-analysis guided by the premise that the functional network underlying these multifactorial syndromes is under selective genetic pressure. This approach drastically reduced the genomic region of interest, i.

HELLP babies link a novel lincRNA to the trophoblast cell cycle.

The HELLP syndrome is a pregnancy-associated disease inducing hemolysis, elevated liver enzymes, and low platelets in the mother. Although the HELLP symptoms occur in the third trimester in the mother, the origin of the disease can be found in the first trimester fetal placenta. A locus for the HELLP syndrome is present on chromosome 12q23 near PAH.
