Abstract
|
|
|
|
In vitro fertilization (IVF) is a main option for the infertility treatment and its major concerns are the risk of multiple pregnancy, preterm delivery, intrauterine growth retardation (IUGR), and congenital malformation. Russell-Silver syndrome (RS) is a congenital disorder characterized by intrauterine and postnatal growth retardation associated with inverted triangular face, clinodactyly, and asymmetry of the body. The possibility of genomic imprinting defect has been suggested because the risk of RS syndrome is increased after IVF like other imprinting defect disorders such as Angelman or Beckwith-Wiedemann syndrome, and the major epigenetic disturbance of RS syndrome is the hypomethylation of the imprinting in 1 lp15. We report three cases of RS syndrome in one of IVF twins with a review of the literature.
