Natera Panorama Practice Exam

Panorama’s whole chromosome screen is designed to detect fetal copy-number changes across entire chromosomes, focusing on the most common and clinically important aneuploidies. It targets autosomal trisomies 21, 18, and 13; monosomy X (Turner syndrome); sex chromosome trisomies (such as XXX, XXY, XYY); and triploidy (an extra complete set of chromosomes). This combination covers the broadest, clinically relevant spectrum for a whole-chromosome assessment, which is why that option is the best choice. Other options miss one or more of these categories—for example, omitting triploidy or including a chromosome finding not typically reported by this screen (monosomy Y).
