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.

Imprinting disorders are caused by genetic defects or epigenetic mutations (DNA methylation); i.e., aberrant DNA methylation of differentially methylated regions (DMRs) that regulate allele-specific expression of imprinted genes . The relationship between ART and aberrant genomic imprinting is … Zobacz więcej We conducted a Japanese nationwide epidemiological study of four imprinting disorders to determine associations with ART. We contacted a total of 2777 pediatric departments of all hospitals that were identified … Zobacz więcej To investigate whether disease phenotypes in patients could be altered by ART, we compared the clinical features in detail. There were no major differences overall between … Zobacz więcej We annotated genomic regions and then identified the DNA methylation variation (DMVs) showing absolute methylation changes ≥ 7.5% and statistically significant differences (false discovery rate (FDR) < 0.05) in the ART … Zobacz więcej To investigate the genome-wide DNA methylation changes in ART-SRS patients, we performed reduced representation bisulfite sequencing (RRBS) to produce DNA … Zobacz więcej Witryna7 cze 2003 · ARTs now account for between 1% and 3% of annual births in many western countries and in-vitro fertilisation (IVF) services are growing worldwide.
