Chromosomal Microarrays in Prenatal Diagnosis: Time for a Change of Policy?
Microarrays have replaced conventional karyotyping as a first-tier test for unbalanced chromosome anomalies in postnatal cytogenetics mainly due to their unprecedented resolution facilitating the detection of submicroscopic copy number changes at a rate of 10-20% depending on indication for testing. A number of studies have addressed the performance of microarrays for chromosome analyses in hig...

Chromosomal microarray versus karyotyping for prenatal diagnosis.
BACKGROUND Chromosomal microarray analysis has emerged as a primary diagnostic tool for the evaluation of developmental delay and structural malformations in children. We aimed to evaluate the accuracy, efficacy, and incremental yield of chromosomal microarray analysis as compared with karyotyping for routine prenatal diagnosis. METHODS Samples from women undergoing prenatal diagnosis at 29 c...
متن کاملPrenatal Diagnosis of Triploidy in Fetus with Unexpected Chromosomal Translocation of Maternal Origin
Triploidy is a lethal chromosomal abnormality. Foetuses with triploid condition have a tendency to die in early conception and very few survive to term. In this study, we report the prenatal diagnosis of fetal triploidy with unexpected chromosomal translocation. A 27 years old women was referred to our clinical cytogenetic department due to history of previous conceptus with intrauterine growth...
متن کاملPRENATAL DIAGNOSIS OF CHROMOSOMAL DISORDERS - molecular aspects
It is known that perinatal mortality is caused in 20-25 percent of cases by inhaerited anomalies of fetuses and many of theese might be explained by genetic disorders. In general genetic disorder is a condition caused by abnormalities in genes or chromosomes. Chromosomes are complex bodies in cell nucleus as carriers of genes. While some diseases are due to genetic abnormalities acquired in a f...
