Single-cell copy number varation detection

ABSTRACT: Detection of genomic rearrangements from a single cell instead of a population of cells is an emerging research technique with important applications in the study of human fertility, constitutional chromosomal disorders, and tumor progression. Here, we develop a method to improve the detection of single-cell genome-wide copy number variation. At this study, 7 amplified single cell DNA samples derived from EBV-line [47,XY,+21], [46,XY,der(20),t(18;20)(p11.21;p13)], [46,XX,del(18)(p11.21->pter)], [46,X,der(X),t(X;14)(q21.1;q12.2)] were analyzed by Agilent 244K array CGH. For these single cell Agilent 244K array CGH analyses: non-amplified genomic DNA extracted from the blood of a Klinefelter patient (XXY) was used as a reference sample. As a validation, the corresponding non-amplified
