Polymorphisms in the tumor necrosis factor-α gene at position -308 and the inducible 70 kd heat shock protein gene at position +1267 in multifetal pregnancies and preterm premature rupture of fetal membranes
Fetal Membranes, Premature Rupture
HSP70 Heat-Shock Proteins
Tumor Necrosis Factor-alpha
Tumor necrosis factor-alpha allele 2 and/or heat shock protein-70 allele 2 carriage by the first-born fetus is associated with preterm premature rupture of membranes in multifetal pregnancies.
