As described in Chaubey et al., Journal of Molecular Diagnostics, vol. 22, No. 6 June 2020, they used 10x WGS and validated that the NxClinical algorithm detected all CNVs and AOH that were found by high-resolution SNP arrays. Figure 2. shows a small exonic deletion detected using 10x WGS with the MSR algorithm. With higher depth NGS, smaller CNVs can be detected and integrated with sequence ...

The probe track view in NxClinical shows greater detail related to the supporting probes involved in this heteroUPD15 example. Enlarge the image to the right to reveal the heteroUPD15 visualized on both the top chromosome view (represented by the pink horizontal line) and the BAF plot for parental informative SNPs ...

Within the karyogram view, vertical bars are drawn within the AOH affected chromosome(s) to indicate parent-of-origin (pink=maternal; blue=paternal), and the same color indicators are displayed in the zygosity track. The image to the left displays a maternal inheritance represented by the pink probes on the BAF ...

The MSR algorithm can also be applied to detect CNVs from shallow sequencing, including very low-level mosaic events seen in NIPS or ctDNA samples. The image below shows a sample with trisomy 21 detected using 1x WGS. CNVs are an important contributor to disease and are required for accurate diagnosis. For clinical sequencing to be fully accepted as a replacement for microarrays and other ...

The MSR algorithm can be applied to any gene panel from single gene (e.g. DMD test) to large panels having thousands of gene. The image below is from the Illumina TruSightTM Oncology 500 (TSO500) panel showing a somatic cancer profile. The cytogenetic complexity of the tumor sample is clearly evident with a large copy number gain of 8p and loss of a large section of 13q. Aberrations associated ...

BioDiscovery has developed two algorithms for the detection of CNV and AOH events from NGS using its decades-long expertise in the area. One algorithm, the “Self-reference” algorithm, can be used for all WGS data regardless of sequencing depth. The second is the “Multi-Scale Reference” (MSR) algorithm that is applicable to all NGS data (WGS, WES, and Gene panels). The MSR ...

Getting CNV calls from Whole Exome Sequencing has been one of the most challenging efforts in the community. There have been numerous algorithms proposed but they suffer either from poor sensitivity or too many false-positive calls. The MSR algorithm has been able to offer the best balance of these competing measures, detecting small true-positives without generating many false-positives. The ...
