This adds a parental report with secondary findings to a whole genome sequencing trio test. Please note, appropriate selection must be made on the test requisition form as well as the consent in order to generate parental reports. Additionally, only pathogenic or likely pathogenic variants will be reported.
Whole genome sequencing is performed on genomic DNA by short-read next-generation sequencing (NGS). Coverage requirements are based on validation data. An exon is considered fully covered if all coding bases plus three nucleotides of flanking sequence on either side are covered. Revvity Omics has curated deep intronic pathogenic variants from public databases; these are tagged for identification during analysis. Alignment to the human reference genome is performed, and annotated variants are identified. Variants are reviewed based on minimum coverage and alternate allele frequency cut offs defined as per laboratory procedure. Indel and single-nucleotide variants (SNVs) may be confirmed by Sanger sequencing analysis before reporting, based on laboratory requirements. Mitochondrial DNA is sequenced and analyzed using the same pipeline. Genes and/or exons with nonunique sequences, such as those containing pseudogene regions, are not analyzed in this assay.
Copy number variation (CNV) analysis detects deletions and duplications; however, in some instances, due to exon size, sequence complexity, or other factors, certain CNVs may be difficult to detect and analyze. This assay does not interrogate CNVs in mitochondrial DNA. CNV analysis will not detect tandem repeats, balanced alterations (reciprocal translocations, Robertsonian translocations, inversions, and balanced insertions), methylation abnormalities, triploidy, or genomic imbalances in segmentally duplicated regions. This assay is not designed to detect mosaicism; however, possible cases of mosaicism may be detected and reported if laboratory requirements are met.
Primary data analysis is performed using standard FASTQ conversion tools appropriate to the sequencing platform. Secondary analysis is conducted using a high-performance genomic analysis pipeline. Tertiary analysis incorporates established annotation tools together with Revvity Omics' internal software. Copy number variation and absence of heterozygosity assessments are performed using a clinical cytogenomics platform. SMA testing and repeat expansion disorder screening are performed using in-house bioinformatics tools based on published literature with modification (PMID: 28125085, 32092542, 28887402).
