The coding sequences and intron-exon boundaries of the complement factor H (CFH), complement factor I (CFI), Membrane Cofactor Protein (MCP), complement factor B (CFB) and C3 were sequenced in 33 women with a diagnosis of HELLP syndrome.

FASA-670G and Fas ligand IVS2nt A 124G polymorphisms are significantly increased in women with pre-eclampsia and may contribute to HELLP syndrome: a case-controlled study.
A single A>G nucleotide substitution at position -670 in the maternal but not neonatal TNFRSF6 gene coding for Fas is associated with a higher risk for HELLP syndrome.
Schlembach and co-workers in this issue of Clinical Science have studied the association of maternal and/or fetal factor V Leiden (FVL) and prothrombin G20210A gene mutation with HELLP syndrome and intrauterine growth restriction (IUGR) to confirm whether these genetic mutations are important risk factors for the pathogenesis of the HELLP syndrome, leading to an inadequate maternal-fetal circulation.
We measured serum levels of total and fetal circulating cell-free DNA (cfDNA), soluble endoglin, soluble form of vascular endothelial growth factor receptor, and placental growth factor in a healthy control group of pregnant women (n = 26), patients with mild (n = 37) and severe PE (n = 25), and patients with HELLP syndrome (n = 16).
As hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome is one of the most severe forms of pre-eclampsia we aimed to assess the prevalence of the factor V Leiden, the prothrombin 20210G >A mutation and the methylenetetrahydrofolate reductase (MTHFR) 677C >T polymorphism in women with HELLP syndrome and in their fetuses from the same index pregnancy.
To assess whether the high soluble fms-like tyrosine kinase-1 (sFlt-1) to placental growth factor (PlGF) ratio is associated with adverse outcomes (e.g., HELLP syndrome [hemolysis, elevated liver enzymes, and low platelets], severe hypertension uncontrolled by medication, non-reassuring fetal status, placental abruption, pulmonary edema, growth arrest, maternal death, or fetal death) and a shorter duration to delivery in early-onset fetal growth restriction (FGR).
This review explores the causative relationship of a fetal disorder of mitochondrial fatty acid oxidation, long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency, and the serious maternal liver diseases of pregnancy-preeclampsia, the HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet counts), and acute fatty liver of pregnancy.
Several studies have shown overexpression of leptin in microarray experiments in pre-eclampsia (PE) and in hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome.
Because of this, we studied the frequency of the common LCHAD mutation in the Dutch population by analyzing 2,047 Guthrie cards and 113 women who had suffered from HELLP syndrome.
Our aim was to compare the tetranucleotide repeat (TTTC)(n) polymorphism in the 3'-flanking region in the LEP gene on DNA samples from patients with pre-eclampsia (PE), hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome and healthy pregnant controls.
We found that: 1) Placental LEP and FLT1 expression was up-regulated in preterm preeclampsia with or without HELLP syndrome compared to controls; 2) Mean pp38 immunoscore was higher in preterm preeclampsia, especially in cases with HELLP syndrome, than in controls.

Our experimental results show the AT1-AA titer and positive rate were significantly higher in HELLP group, and AT1-AA titer were positively correlated with the level of TNF-α and ET-1 in plasma and the grade of HELLP syndrome.
