NGS sample quality metrics

Sequencing error rate

Sequencing error rate refers to the frequency at which incorrect base calls are made during sequencing process.

Blue bars represent each of these parameters per sample, while a vertical line represents a general metric across all the samples of the same case type in the account.

Call rate

The Call rate field displays the percentage of loci on the array for which a genotype call was successfully made.

Call rate is one of the key metrics used to determine array sample quality, alongside log R deviation.

A high call rate indicates a high-quality sample and successful genotyping. Low call rates can signify problems with the DNA sample (poor quality or quantity) or issues during the array processing.

Displayed to three decimal places.

CNV overall ploidy

The CNV overall ploidy field displays the ploidy value extracted from the CNV VCF header. If no CNV VCF file is provided, "N/A" is displayed.

Displayed to three decimal places.

circle-exclamation

The value is shown as is. The system does not validate or flag abnormal ploidy values. Interpret ploidy in context.

Percentage of mapped reads

Percentage of reads mapped to the reference sequence.

Blue bars represent each of these parameters per sample, while a vertical line represents a general metric across all the samples of the same case type in the account.

Array sample quality metrics

Autosomal call rate

The Autosomal call rate field displays percentage of loci on the array for which a genotype call was successfully made, that only includes autosomes.

A high call rate indicates a high-quality sample and successful genotyping. Low call rates can signify problems with the DNA sample (poor quality or quantity) or issues during the array processing.

    NGS sample quality

    The overall sample quality indicator provides a quick assessment of sequencing reliability for each sample.

    Sample quality is evaluated using the following metrics:

    • Average depth of coverage Mean coverage across the target regions

    • % bases covered >20x Percentage of bases in the target regions covered at a depth greater than 20×, indicating reliable coverage

    • Error rate Sequencing error rate. Reflects general sequencing accuracy

    • % mapped reads Proportion of reads successfully mapped to the reference genome

    • Contamination check Detects mixed or low-quality samples that may affect interpretation

    These metrics give an overall confidence level for whether the sequencing data can support accurate variant interpretation.

    Log R deviation

    The Log R Deviation (or Log R Ratio standard deviation) quantifies the variability of the the signal intensity for each SNP marker on an array, ie, noise level.

    Log R deviation is one of the key metrics used to determine array sample quality, alongside call rate.

    Lower values indicate more consistent signal intensities. A high Log R Deviation can indicate a poor-quality sample or potential issues with CNV calling.

    Contamination

    The Contamination column reports whether a sample shows signs of DNA contamination, helping ensure data reliability before interpretation.

    circle-info

    Be mindful that when contamination is suspected in sequencing data, it could stem from various sources, including true contamination, sample mix-up, library preparation issues, or technical artifacts.

    Always confirm the issue with other quality checks.

    Contamination is detected using Peddyarrow-up-right calculations, which estimate the proportion of reads that do not match the expected genotype. This estimate is based on the idr_baf score.

    idr_baf stands for the interdecile range of the B-allele frequency—calculated as the difference between the 90th and 10th percentiles of the distribution of alt / (ref + alt) ratios across all variant sites.

    A larger idr_baf value indicates greater variability in allele balance, which may suggest sample contamination, particularly from another human DNA sample.

    Contamination check results:

    • N/A No data is available (older cases or when idr_baf = 0.000).

    • No No contamination detected (idr_baf < 0.200).

    • Unlikely Possible contamination, but evidence is weak (0.200 ≤ idr_baf

    circle-check

    Hover over the value to display a tooltip showing the HET ratio (proportion of sites that are heterozygous) and the HET count (number of heterozygote calls in sampled sites).

    circle-check

    Tips:

    • Always review contamination results before starting interpretation to rule out technical issues that could explain unexpected variant calls.

    triangle-exclamation

    Warnings:

    • Panels may be less reliable: For targeted panels, contamination estimates may be inaccurate due to the limited number of variants available for calculation. Use caution and cross-check with other QC metrics when interpreting these results.

    *In Emedgene, the terms "incidental findings" and "secondary findings" both refer to secondary findings as defined by the ACMG, due to historical usage.

    When Emedgene was first released, the term “incidental findings” was adopted in alignment with the clinical genomics standard at the time. The 2013 ACMG recommendations defined incidental findings as “the results of a deliberate search for pathogenic or likely pathogenic alterations in genes that are not apparently relevant to a diagnostic indication for which the sequencing test was ordered” (PMID: 23788249).

    As the field evolved, the ACMG and broader clinical community began to distinguish between “incidental findings” (unexpected, not actively sought) and “secondary findings” (intentionally analyzed and reportable). This shift was reflected in the updated 2016 ACMG guidance (PMID: 27854360).

    To reflect this change, Emedgene introduced the term “secondary findings” into the platform. However, “incidental findings” remains in use throughout the platform for technical consistency.

    IBS0

    Identity by state 0—a number of genomic loci where two individuals share zero alleles. This occurs when the two individuals are opposite homozygotes for a biallelic SNP.

    This metric is calculated across a set of biallelic SNPs and is inversely related to the degree of genetic similarity between the individuals. A low IBS0 count suggests a higher degree of overall genetic similarity, but it is an indirect and limited measure of genetic relatedness that requires interpretation alongside other metrics.

    Relationship validation result

    Summarizes the outcome of the relationship validation, confirming whether the observed data aligns with the expected pedigree structure.

    hashtag
    Relationship validation calculation

    Relationship validation is done by Peddyarrow-up-right based on:

    • Relatedness coefficient (𝑟)—a measure of how much two individuals share alleles from a common ancestor, indicating the probability that alleles at the same genome location are identical by descent

    • IBS0 (Identity by state 0)—a number of genomic loci where two individuals share zero alleles, ie, they are opposite homozygotes

    • IBS2 (Identity by state 2)—a number of genomic loci where two individuals share two alleles, meaning they have the exact same genotype

    Peddy takes the inferred relationships from the genetic data and cross-references them against the declared relationships. For every pair of individuals in a cohort, Peddy calculates a coefficient of relatedness from the genotypes observed at the sampled sites.

    For each possible pair of samples in a pedigree, the expected relatedness coefficient based on declared family relation is compared with the observed relatedness coefficient (𝑟). IBS0 value helps to differentiate between sibling and parent–child relationships, both expected to have ~50% relatedness coefficient (see table).

    The proband phenotype is exactly the same as one listed in the disease’s clinical description.

    Match by ascendance/descendance

    The proband phenotype is a direct ancestor or descendant of a disease phenotype in the Human Phenotype Ontology (HPO) hierarchical tree, up to 7 steps apart.

    Indirect match

    The proband phenotype lies within a 4-step range in the HPO graph from the disease phenotype but is not its direct ancestor or descendant. While indirect match may highlight potential connections, we advise users to interpret it carefully because it may include phenotypes from different branches of the HPO ontology that are not biologically related.

    No match

    The proband phenotype does not appear in the disease’s phenotype list and is not connected to it within the range of match by ascendance/descendance and indirect match.

    Phenotypic match models

    Proprietary phenotypic match models assess how closely a gene’s associated disease phenotype matches the patient’s phenotype profile. A degree of similarity is resembled by the phenotypic match score. The phenotypic match score indicates the degree of similarity between the patient’s phenotype set and the phenotype set of the best-matching gene-related disease.

    If a gene is linked to multiple diseases, the model compares the patient’s phenotypes with each disease profile individually. The highest score determines the best match, and this disease is automatically displayed in the Evidence graph. The Phenomatch and Phenomeld scores shown in the variant table correspond to this best-matching disease, even if the associated disease is manually updated.

    An Emedgenizer is a logic-based tool designed to normalize quality parameters in the VCF output from a specific , ensuring alignment with Emedgene internal format. An Emedgenizer is specific to the variant caller, its version, and the calling methodology used.

    All Emedgenizers are grouped and versioned within an Emedgenizer Plugin.

    Typically, the Emedgenizer Plugin version used for a case aligns with the pipeline version that processed it. However, updates to existing normalization logic, bug fixes, or the addition of support for new callers or methodologies may require updating or creating new Emedgenizers, which in turn necessitates a new plugin version. These changes are generally reflected in a minor version update of the Emedgenizer Plugin.

    Custom Presets

    When you apply a Preset, you can refine it further by running a search on top of the filtered results. This creates a real-time sub-filter without changing the original Preset.

    Example: If your Preset is based on a gene list with multiple genes and returns many variants, you can search for a single gene within that list. The results will then display only variants from that specific gene.

    If this refined view is useful for future cases, you can save it as a Custom Preset.

    Marking a Preset as Reviewed

    When you have completed reviewing all variants within a Preset, you can mark it as Reviewed. This feature makes it clear which Presets have already been addressed in a case, helping teams avoid re-checking the same variants.

    Once marked, the Preset will display a visual indicator in the Presets panel. You can still reopen and apply the Preset at any time if you need to revisit it.

    circle-check

    Tips:

    • Use Viewed/Unviewed filters in Presets to avoid re-checking the same variants.

    • Use marking a preset as reviewed feature in collaborative workflows so team members know which Presets have already been covered. If your SOP requires multiple reviewers, the Preset can be revisited even after being marked as reviewed.

    • Combine search and filters: A search applied within a Preset intersects results in real time (e.g., narrow a multi-gene preset to a single gene).

    • Use Search Intersect to quickly narrow large gene lists without editing the original Preset.

    • Save refined results as Custom Presets to reuse them in similar cases.

    • Combine multiple searches for stepwise filtering when reviewing complex datasets.

    Case statuses in a case lifecycle

    In Emedgene, case status indicates the current stage of a case—from data upload through analysis, review, and results finalization. Statuses are assigned either automatically by the system or by authorized users, depending on the workflow stage and user permissions.

    Different statuses require different IAM scopes/Emedgene roles for assignment and reassignment.

    Case statuses are grouped into three categories based on control type:

    • System-controlled: Assigned automatically by the system; cannot be reassigned by users.

    • User-controlled: Assigned and reassigned by authorized users.

    • System-assigned, user-reassignable: Assigned automatically by the system but can be reassigned by authorized users.

    Case statuses by origin:

    • Out-of-the-box: Default options provided by the platform.

    • Custom: to align with specific workflows.

    • You are complementing NGS results with findings from other genetic tests (e.g., long-read sequencing, optical mapping, CGH, SNP array, karyotyping/FISH, repeat-primed PCR, MLPA, Southern blot, etc.)

    • You wish to report on adjacent CNV calls as a single CNV event.

    • You wish to report a set of adjacent variants together as a single multi-nucleotide variant (MNV).

    Manually adding variants ensures that all relevant findings are visible in the case review and can be considered during interpretation.

    Currently supported variant types: SNV, CNV, UPD, ROH, and STR.

    circle-info

    Note: SV support is planned for future releases.

    hashtag
    Additional considerations:

    • When updating HPO terms, older terms may not map automatically in reanalysis. Review carefully before finalizing.

    • After reanalysis, some input files may not appear immediately in the Versions tab.

    • Editing interpretation notes may create an activity entry labeled as reanalysis. This does not affect case results but may appear in the audit trail.

    • If you replace the gene list, the original list is not displayed in the Activity log.

    circle-check

    hashtag
    Tips:

    • Always check whether your edit will trigger reanalysis before proceeding.

    • Keep edits to delivered cases within the supported fields to avoid errors.

    • For sensitive inputs (like phenotypes or gene lists), plan to rerun the case to ensure results reflect the most up-to-date information.

    • If uncertain, use the Save option first, then decide if reanalysis is needed.

    Genes coverage section

    The Genes coverage section helps you quickly identify parts of genes that may not have been adequately sequenced in your case. This insight is particularly important when assessing sequencing quality, interpreting uncertain findings, or deciding if further validation is needed.

    While variant callers provide base-by-base coverage, Emedgene simplifies the view by showing average coverage per region. This makes it easier for you to spot undercovered genes at a glance, even when individual positions may appear sufficiently covered. By smoothing out local fluctuations, average coverage helps you prioritize regions that might require further review and complements DRAGEN's fine-grained metrics with a broader, more interpretable view.

    hashtag
    How coverage is calculated

    Coverage metrics are generated differently depending on the type of input data used for your case:

    1. FASTQ / BAM or gVCF-based cases

    • If your case was started from FastQ/BAM or gVCF, coverage is inferred from gVCF reference blocks (also called GVCFBlocks).

    • These blocks are segments of the genome where genotype quality (GQ) is consistent.

    • A new block is created whenever there's a significant change in GQ, which results in a highly segmented and detailed representation of local sequencing quality.

    2. VCF + BAM or VCF + BED-based Cases

    • If your case includes VCF and BAM or VCF and BED, coverage is calculated directly from the aligned reads or from predefined BED intervals.

    • Coverage is calculated as the true base-by-base average across the entire region.

    • This method avoids the variability of gVCF segmentation and gives a precise coverage profile for each region.

    circle-check

    Tip: Before comparing coverage values across cases, check whether the case was processed from FASTQ/gVCF or VCF with alignment files (BAM/CRAM). The calculation method differs, so values may not be directly comparable.

    circle-exclamation

    Limitation: Coverage estimation is not supported for VCF + CRAM cases. If a CRAM file is used with a VCF file, as opposed to a BAM or a BED file, the Genes Coverage table will remain empty for virtual panel cases.

    hashtag
    Regions evaluated for coverage

    Coverage is compared against expected regions defined in:

    • Emedgene's reference BED file, or

    • Your test’s custom KIT BED file

    Each region is defined by:

    • Chromosome

    • Start & end positions

    • Name and strand (Optional)

    hashtag
    Coverage assessment

    Emedgene uses the tool bedtools intersect to compare each expected region from the regions used for coverage assessment against actual read coverage. The system captures:

    What's included in the Evidence Page?

    hashtag
    Variant information

    Displays the main effect, HGVS nomenclature, zygosity (HET, HOM, HEMI, or REF), and de novo status if applicable.

    hashtag
    Gene information

    Gene symbol, if the gene is tolerant to variation, and assumed inheritance mode in the case under review. This is suggested based on the observed level of genotype-phenotype co-segregation and inheritance mode of the genetic condition (reported or suspected).

    In addition to the conventional inheritance modes (Autosomal Dominant, Autosomal Recessive, Compound Heterozygote Autosomal Recessive, X-Linked Dominant, X-Linked Recessive), the platform also employs Autosomal Dominant Partial Penetrance and Partial Autosomal Recessive designations.

    Autosomal Dominant Partial Penetrance is used when the gene-associated condition is AD, and the variant is Het in the test subject and at least one of their parents. This suggests that the phenotypes may be due to incomplete penetrance of the genetic condition.

    Partial Autosomal Recessive is used when the gene-associated condition is AR and the variant in the test subject is Het. This helps to account for the possibility that another causative variant is undetected - in the same (compound heterozygosity) or another (digenic inheritance) gene.

    hashtag
    Disease information

    Name of the condition as sourced from OMIM, literature, or other databases. When multiple diseases are associated with a gene, users can manually select the one most relevant to the case or choose to add a custom disease.

    hashtag
    Patient phenotypes

    Proband's phenotypes that match phenotypes reported for the suspected disease. Exact, indirect, and matches by ascendance are considered.

    Coverage for a region is based on the median coverage of each gVCF block. If a region spans multiple blocks, the reported value is the average of those medians.

  • Within a region (like an exon), you’ll often see multiple blocks. Emedgene aggregates them to show you:

    • Average depth

    • Minimum depth

    • Depth range

  • Occasionally, some blocks may be unusually large and may miss internal variation—for example, in genes like XIAP, one block could span an entire region despite having uneven coverage inside.

    STR calling and interpretation

    hashtag
    Calling methodology

    Emedgene uses ExpansionHunter by DRAGEN to call short tandem repeats (STR), also known as repeats expansions.

    Thirty clinical genes associated with diseases caused by repeat expansion are called in DRAGEN version 3.9arrow-up-right and presented in the platform. Those genes are: AFF2, AR, ATN1, ATXN1, ATXN10, ATXN2, ATXN3, ATXN7, ATXN8OS, C9ORF72, CACNA1A, CBL, CNBP, CSTB, DIP2B, DMPK, FMR1, FXN, GIPC1, GLS, HTT, JPH3, NIPA1, NOP56, PABPN1, PHOX2B, PPP2R2B, RFC1, TBP, TCF4.

    STR calling with ExpansionHunter

    hashtag
    Spanning reads

    Exact sizes of short repeats are identified from spanning reads that completely contain the repeat sequence.

    hashtag
    Flanking reads

    When the repeat length is close to the read length, the size of the repeat is approximated from the flanking reads that partially overlap the repeat and one of the repeat flanks.

    hashtag
    In-repeat reads (IRRs)

    If the repeat is longer than the read length, its size is estimated from reads completely contained inside the repeat (in-repeat reads). In-repeat reads anchored by their mate to the repeat region are used to estimate the size of the repeat up to the fragment length. When there is no evidence of long repeats with the same repeat motif elsewhere in the genome, pairs of in-repeat reads can also be used to estimate the size of long (greater-than-fragment-length) repeats.

    circle-info

    Note: ExpansionHunter for STR calling is designed for use in PCR-free WGS only. While STR variants might be called in exome cases, the limitations are currently unknown and it is therefore not recommended for use.

    hashtag
    Recommendation for interpretation

    In light of our recent experience and an internal investigation by the Illumina’s scientific team, we believe it is appropriate to enable prioritization for a subset of STR loci, but not all loci typed by DRAGEN. This is due to technical genotyping challenges and/or lack of scientific evidence of pathogenicity for the remaining loci. Current list of genes where STR may be tagged when appropriate is provided below:

    In silico predictions filters (v37.0+)

    Prepare DRAGEN QC metrics files to be included in a NGS VCF case

    When creating NGS cases that start from VCF, you can create a browsable DRAGEN QC report from the DRAGEN metrics files. Due to security restrictions, CSV files are not directly ingested, but they can be included when packaged in a TAR file.

    1. Navigate to local directory containing metrics files for a specific sample.

    2. Define sample name as a variable samplename="NA12878".

    3. Combine the find and tar commands to package the files into a tar.gz file with the following extension *.metrics.tar.gz. Command to find files matching the required patterns:

    1. Upload the metrics.tar.gz file to the storage location used for creating cases.

    2. Add metrics.tar.gz to case creation API JSON payload using the corresponding storage ID. Ensure that if the extension is not contained in the filename (e.g. files from BaseSpace) that "sample_type": "dragen-metrics" is set within the JSON payload.

    chevron-rightCase creation API JSONhashtag
    1. DRAGEN report link is then available once your case has been delivered.
