Imprinting disorders (IDs) are a group of rare congenital diseases affecting growth, development and metabolism with a lifelong impact on patients quality of life. Despite their common underlying (epi)genetic aetiologies, IDs are usually studied separately by small groups working in isolation, and the basic pathogenesis and long term clinical Imprinting Disorders IVF Risks In vitro fertilization (IVF), the process of fertilizing an egg with sperm outside of the body, is a technique that has enabled couples with fertility problems to conceive.
How can the answer be improved? The cause for a higher rate of imprinting disorders is not clear, though recent articles have suggested an association with ovarian stimulation, the type of culture media used, and the length of culture time (specifically, to the blastocyst stage). 16. 2 Imprinting Disorders Following In Vitro Fertilization (IVF) Model imprinting disorders are individually and collectively extremely rare.
Reports that one of these disorders, Angelman syndrome, was diagnosed in several children conceived by IVF, was therefore interpreted as a possible indication that assisted reproductive technology may have In vitro fertilization (IVF) appears to increase the risk of Angelman syndrome as a result of a genetic mechanism known as an imprinting error, according to a study of IVF pregnancies. Several studies have indicated that IVF is accompanied by an increased risk of certain conditions with imprinting disorders, such as Angelman, Beckwith In 2005, a cohort study was published investigating the occurrence of imprinting disorders after IVF in the Danish population.
Using a Denmark National Registry of 25 000 children born after IVF, no Angelman syndrome cases were identified, arguing against an association of IVF with Angelman syndrome [ 21. Are imprinting disorders more prevalent after human in vitro fertilization or intracytoplasmic sperm injection? Jan P. W.
Vermeiden, Ph. D. Mar 01, 2013 CONCLUSION(S): Imprinting disorders are more prevalent after human IVF or ICSI. Future studies should correct for fertility problems in the affected and comparison groups. It is highly improbable that assisted reproduction technologies cause imprinted diseases in humans. To our knowledge, this is the first systematic historical followup study on IVF children and a control group of children without prior IVF specifically focusing on imprinting diseases.
The diagnosis of imprinting diseases, however, is difficult.
