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 a 7q21.13q22.1 deletion detected using high-resolution microarray
We report a case of de novo 7q interstitial deletion detected by conventional karyotyping and by microarray of amniotic fluid sampled during the prenatal period. A 32-year-old pregnant woman was evaluated at our hospital following detection of increased nuchal translucency at 12 weeks and 5 days of gestation. Conventional karyotyping revealed 46,XX,del(7)(q21q22) in 20 interphase mitotic cells,...
متن کاملThe Use of Chromosomal Microarray Analysis in Prenatal Diagnosis.
Chromosomal microarray analysis (CMA) identifies microdeletions and duplications undetected on karyotype analysis. Copy number variants (CNVs) occur in 1% to 1.7% of all pregnancies, with clinical implications. All women undergoing invasive testing for routine indications should be offered microarray. Clinically significant CNVs are seen in approximately 6% of pregnancies with ultrasound anomal...
متن کاملPrenatal diagnosis of sex chromosomal inversion, translocation and deletion
The aim of the present study was to perform comprehensive prenatal diagnosis using various detection techniques on a fetus in a high‑risk pregnant woman, and to provide genetic counseling for the patient and her family so as to avoid birth defects. The routine karyotype analysis via amniocentesis, fluorescence in situ hybridization, and whole genome microarray technique were performed for the p...
متن کاملClinical implementation of chromosomal microarray technology in prenatal diagnosis. (Review).
Chromosomal microarray technology represents the technical convergence of molecular genetics and cytogenetics, and is rapidly revolutionizing modern cytogenetics. Expected genomic aberrations are accurately identified and provide readily interpretable results that are suitable for clinical risk stratification and therapeutic strategies. The applic...
