We used placental tissue to compare the imprinted gene expression of IGF2, H19, KCNQ1OT1, and CDKN1C of singletons conceived via assisted reproduction technology (ART) with that of spontaneously conceived (SC) singletons. Of 989 singletons examined (ART n = 65; SC n = 924), neonatal weight was significantly lower (P < .001) in the ART group than in the SC group, but placental weight showed no s...
It is already three decades since the birth of the first “test-tube baby” in 1978 and such methods have found their due place in most countries. In Denmark alone, more than 6% of children are born through assisted reproduction technologies (ARTs) (1). In the United States, more than 50,000 babies are born through IVF annually and there are more than 4 million people born through such methods ar...
Beckwith-Wiedemann syndrome (BWS) is a model imprinting disorder resulting from mutations or epimutations affecting imprinted genes on chromosome 11p15.5. The classical clinical features of BWS are macroglossia, preand/or postnatal overgrowth, and anterior abdominal wall defects (umbilical hernia or exomphalos). Additional more variable features include hemihypertrophy, neonatal hypoglycaemia, ...
