Chromosomal microarrays testing in children with developmental disabilities and congenital anomalies
OBJECTIVE For fetuses with a diagnosis of right aortic arch and normal cardiac anatomy, we aimed to establish the frequency of chromosomal anomaly diagnosed with single nucleotide polymorphism microarray analysis, particularly focusing on microduplications or microdeletions which would have gone undetected by conventional karyotyping and six-probe fish (13,18,21, X,Y, TUPLE). METHOD Retrospec...
OBJECTIVES To report our experience over the past 10 years of chorionic villi sampling (CVS) prenatal diagnosis in a high-risk population for chromosomal anomalies, and to analyze, according to the results, the advantages and disadvantages of using quantitative fluorescence polymerase chain reaction (QF-PCR) in amniotic fluid with respect to a conventional semi-direct cytogenetic CVS method in ...
OBJECTIVE To ascertain the incidence, and describe the various forms of neural tube defects (NTDs) due to genetic, chromosomal, and syndromic causes. METHODS We carried out a retrospective analysis of data retrieved from the medical records of newborn infants admitted to the Neonatal Intensive Care Unit with NTDs and their mothers spanning 14 years (1996-2009) at the Security Forces Hospital,...
Background: Congenital anomaly is a disturbance in fetal growth and development during pregnancy and is one of the main causes of morbidity and mortality in the first year of life. In addition, this anomaly causes a large waste of heath care resources. We aimed to determine the prevalence and proportion rates of different congenital anomalies in Iran via a systematic review and meta-analysis.Me...
