Imprinting disorders and ivf

Witryna19 cze 2014 · Congenital imprinting disorders [BWS, AS, PWS (Prader–Willi syndrome; NIM176270) and SRS (Silver–Russell syndrome; NIM180860)] are rare diseases. It is known that they are caused by uniparental disomy (UPD), duplications, gene mutation (deletion), and aberrant DNA methylation in a specific region (Fig. 2 ). WitrynaRecent studies have suggested that babies born from IVF may have a higher rate of certain rare imprinting disorders. Since these disorders are very rare, it has been difficult to determine if there is an association with IVF. Investigators have used rare disease registries to help identify possible risk factors for imprinting disorders.
