Similar disease phenotypes are engendered as a result of the modular nature of gene networks; thus we hypothesized that all human genetic disease phenotypes appear in similar modular styles. Network representations of phenotypes make it possible to explore this hypothesis. We investigated the modularity of a network of genetic disease phenotypes. We(More)
Accurate prediction of survival of cancer patients is still a key open problem in clinical research. Recently, many large-scale gene expression clusterings have identified sets of genes reportedly predictive of prognosis; however, those gene sets shared few genes in common and were poorly validated using independent data. We have developed a systems(More)
Neural tube defects (NTDs) are serious congenital malformation of fusion failure of the neural tube during early embryogenesis. DNA methylation disorders have been found in NTD-affected fetuses, and are correlated to the risk of NTDs. The insulin-like growth factor 2 (IGF2) gene, maternally imprinted, has a key role in fetal development. IGF2 transcription(More)

Folate hydrolase 1 (FOLH1) gene encodes intestinal folate hydrolase, which regulates intestinal absorption of dietary folate. Previous studies on the association between polymorphisms rs202676 and rs61886492 and the risk of neural tube defects (NTDs) were inconclusive. A case–control study of women with NTD-affected pregnancies (n = 160) and controls (n =(More)
BACKGROUND Neural tube defects (NTDs) are one of the most common birth defects caused by a combination of genetic and environmental factors. Currently, little is known about the genetic basis of NTDs although up to 70% of human NTDs were reported to be attributed to genetic factors. Here we performed genome-wide copy number variants (CNVs) detection in a(More)
DNA repair is critical for proper embryogenesis, and altered expression of DNA repair genes has been associated with neural tube defects (NTDs). The expression of DNA repair enzymes may be controlled, in part, by methylation of the promoter region. To assess whether disturbed promoter methylation pattern increases the incidence of NTDs, we employed(More)
Glutamate carboxypeptidase II (GCPII) catalyzes the hydrolysis of N-acetylaspartylglutamate into N-acetylaspartate and glutamate in the brain. Animal experiments suggested that GCPII plays an essential role in early embryonic development. Previous studies provided conflicting results on the effect of the GCPII rs61886492 C>T (or 1561C>T) polymorphism on(More)
