    Invitae Common Hereditary Cancers Panel

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    The Invitae Common Hereditary Cancers Panel is a qualitative high-throughput sequencing based in vitro diagnostic test system intended for analysis of germline human genomic DNA extracted from whole blood for detection of substitutions, small insertion and deletion alterations and copy number variants (CNV) in a panel of targeted genes.

    This test system is intended to provide information for use by qualified health care professionals, in accordance with professional guidelines, for hereditary cancer predisposition assessment and to aid in identifying hereditary genetic variants potentially associated with a diagnosed cancer.

    The test is not intended for cancer screening or prenatal testing. Results are intended to be interpreted within the context of additional laboratory results, family history, and clinical findings.

    The test is a single-site assay performed at Invitae Corporation.

    Device Description

    The Invitae Common Hereditary Cancers Panel uses hybridization-based capture, nextgeneration sequencing (NGS), and a custom-built bioinformatics pipeline to compare all positions in targeted regions of 47 genes to a reference sequence and identify variants, including single nucleotide variants (SNVs), insertions and deletions (Indels), and copy number variants (CNVs). Sequence analysis covers clinically important regions of each gene, including coding exons and 10 to 20 base pairs of adjacent intronic sequence on either side of the coding exons in the transcript listed in Table 1. Genes of "high clinical significance" are defined as those for which the test result(s) may lead to prophylactic screening, confirmatory procedures, or treatment that may incur morbidity or mortality to the patient and are shown in bold text. In addition, the analysis covers the select non-coding variants specifically defined in the table. Any variants that fall outside these regions are not analyzed. Identified variants are assessed by clinical professionals using currently available literature and data from public genetic variant databases. Variants are assigned a score, calculated according to an algorithm that weights the available clinical evidence. Possible outcomes include the following, which are based on joint ACMG/AMP Committee guidelines: Benign (not reported), Likely benign (not reported), Likely pathogenic, Pathogenic, Variant of Uncertain Significance. Variants are reported using HGVS nomenclature and the human reference genome GRCh37.

    AI/ML Overview

    The Invitae Common Hereditary Cancers Panel is a high-throughput sequencing-based in vitro diagnostic test system designed for detecting germline substitutions, small insertions and deletions, and copy number variants (CNVs) in 47 targeted genes. It is intended for use by qualified healthcare professionals for hereditary cancer predisposition assessment and to aid in identifying hereditary genetic variants potentially associated with diagnosed cancer.

    Here's a breakdown of the acceptance criteria and the study proving the device meets them:

    1. Table of Acceptance Criteria and Reported Device Performance

    The acceptance criteria for the Invitae Common Hereditary Cancers Panel are primarily based on the analytical performance metrics of Positive Percent Agreement (PPA), Negative Percent Agreement (NPA), and Technical Positive Predictive Value (TPPV), and Technical Negative Predictive Value (TNPV).

    Performance Metric CategorySpecific MetricAcceptance Criteria (Implicit/Explicit)Reported Device PerformanceComments
    Precision/ReproducibilityOverall PPA (SNVs)No explicit threshold given. High PPA expected.99.95% (95% CI 99.92-99.97%)Meets high precision expectation.
    Overall PPA (Indels)No explicit threshold given. High PPA expected.99.57% (95% CI 99.07-99.80%)Meets high precision expectation. Slightly lower confidence interval than SNVs.
    Overall PPA (CNVs)No explicit threshold given. High PPA expected.99.67% (95% CI 98.80-99.91%)Meets high precision expectation.
    Overall NPA (All variant types)No explicit threshold given. High NPA expected.>99.99% (95% CI >99.99-100%)Excellent negative agreement.
    PPA (Deletions 1-5bp)No explicit threshold given. High PPA expected.97.53% (95% CI 94.72-98.86%)Noted as an exception due to low mappability/complexity region, but still high.
    PPA (SDHA gene for SNVs)No explicit threshold given. High PPA expected.99.15% (95% CI 98.59-99.50%)Slightly lower, but still high.
    PPA (SDHA gene for Indels)No explicit threshold given. High PPA expected.68.42% (95% CI 46.01-84.64%)Significantly lower PPA for this specific gene/variant type, indicating a known limitation.
    PPA (NF1 gene for CNVs)No explicit threshold given. High PPA expected.97.30% (95% CI 90.67-99.26%)Slightly lower, but still high.
    DNA InputOverall Concordance>99% compared to standard input>99.99% for all tested concentrations (5ng/uL, 10ng/uL, 46ng/uL)Meets threshold. 1ng/uL excluded as minimum.
    PPA / NPA>99% compared to standard inputSNVs: 99.9-100%, Indels: 100%, CNVs: 95.1-100%CNV deletions at 5ng/uL were 95.1% (95% CI 83.9-98.7%), slightly below the general >99% expectation.
    Failed SamplesLow number expected.0-6 failed samples depending on DNA input levels.1ng/uL and 46ng/uL had failures, supporting the determined optimal range.
    Analytical Specificity/InterferencePPA / NPA / Concordance for various interferentsNo significant impact on performance expected.Mostly 100% for PPA, NPA, and Concordance.Most interferents did not affect performance. Exceptions for K2EDTA & Wash Buffer on CNVs, and Post-PCR Amplicon on CNVs/Indels were identified as requiring control.
