nstd220 (Chen et al. 2022)

Organism:
Human
Study Type:
Case-Set
Submitter:
Liheng Chen
Description:
This study explored whether adding maternal CNV analysis to NIPT could improve the abnormal detection rate. Using sliding window algorithm counting reads in each continuous bins (100kb size) of each chromosome. We set the thresholds for duplications to be above 2.7 of copy numbers and deletions to be below 1.3 of copy numbers. and were Sequenced with Illumina Nextseq CN550. See Variant Summary counts for nstd220 in dbVar Variant Summary.
