Abstract
Technology provided herein relates in part to non-invasive classification of one or more mosaic copy number variations (CNVs) for a test sample. Technology provided herein is useful for classifying a mosaic CNV for a sample as part of non-invasive pre-natal (NIPT) testing and oncology testing, for example. In particular, a method is provided for classifying presence or absence of genetic mosaicism for a biological sample, the method includes identifying a genetic copy number variation region in sample nucleic acid from a subject, e.g. a pregnant female, determining a fraction of nucleic acid having the copy number variation in the sample nucleic acid, determining a fraction of a minority nucleic acid, e.g. fetal nucleic acid, in the sample nucleic acid, comparing the two fractions to generate a mosaicism ratio, and classifying a presence or absence of a genetic mosaicism for the copy number variation region according to the mosaicism ratio.
