Several genetic factors are involved with recurrent pregnancy loss (RPL). However, few attempts have been made to associate mitochondrial DNA (mtDNA) variations with RPL. Therefore, we investigated the possible effect of the T4216C mutation in the mitochondrial NADH dehydrogenase I (ND1) gene of 33 women with RPL and 100 controls, using polymerase chain(More)
