Mosaic ring chromosome 21, monosomy 21, and isodicentric ring chromosome 21: Prenatal diagnosis, molecular cytogenetic characterization, and association with 2-Mb deletion of 21q21.1–q21.2 and 5-Mb deletion of 21q22.3

Mosaic ring chromosome 21, monosomy 21, and isodicentric ring chromosome 21: Prenatal diagnosis, molecular cytogenetic characterization, and association with 2-Mb deletion of 21q21.1–q21.2 and 5-Mb deletion of 21q22.3

Objective: To present the perinatal findings and molecular cytogenetic characterization of prenatally detected mosaic r(21). Materials, Methods, and Results: A 29-year-old primigravid woman underwent amniocentesis at 22 weeks’ gestation because of hyperechogenic cardiac foci and intrauterine growth...
