Technical Information
Test Confirmation: Help
Single nucleotide variant calls not satisfying 100x depth of coverage and 40% het ratio thresholds are verified by Sanger sequencing (Mu W et al. J Mol Diagn. 2016 Oct 4. PubMed PMID: 27720647). Gross deletion/duplication analysis is performed for all genes using a custom pipeline based on read-depth from NGS … View more
