My Retina Tracker Program Panel

New
Summary
  • Is a 285 gene panel that includes assessment of non-coding variants
  • The My Retina Tracker Program uses the Blueprint Genetics’ Retinal Dystrophy Panel including 285 relevant genes.

    The panel includes excellent coverage of the RPGR ORF15 region, which is critical in retinitis pigmentosa diagnostics.

    The My Retina Tracker Panel includes high resolution copy number variation (CNV) detection that is based on Blueprint’s customized and validated solutions. According to in-house research, approximately 5% of all patients with IRD have a CNV with a large proportion of the CNVs being very small (1-2 exons in size).

    The test offers comprehensive coverage of IRD related non-coding variants that are not included in most commercially available IRD genetic tests.

    The My Retina Tracker Program offers eligible patients in the USA comprehensive genetic diagnostics for their inherited retinal degeneration (IRD). The major inclusion criteria for this program are:

    • The person is clinically diagnosed with one of the inherited retinal degenerative diseases listed on the My Retina Tracker program page.
    • The person lives in the USA.
    • The person has not had any of the following types of genetic testing since 2016:
      1) A test that examined more than 32 IRD-related genes
      2) A whole exome genetic test
      3) A whole genome genetic test
    • The person does not solely have any of the following diagnoses:
      1) Age-related macular degeneration
      2) Glaucoma
      3) Optic neuropathy
      4) Cornea/anterior chamber disease
      5) Diabetic eye disease
      6) Non-genetic ocular or retinal damage diagnosis not listed in the requisition.

Test Limitations

The following exons are not included in the panel as they are not sufficiently covered with high quality sequence reads: CC2D2A (NM_020785:7), CHM (NM_001145414:5), CNGA1 (NM_001142564:2), HK1 (NM_001322365:5), IFT81 (NM_031473:12), KIAA0586 (NM_001244189:6, 33), NEK2 (NM_001204182:8), NMNAT1 (NM_001297779:5), PDZD7 (NM_024895:10), RPGRIP1L (NM_015272:23), SCLT1 (NM_001300898:6), TCTN1 (NM_001173976:2;NM_024549:6). Genes with suboptimal coverage in our assay are marked with number sign (#) and genes with partial, or whole gene, segmental duplications in the human genome are marked with an asterisk (*) if they overlap with the UCSC pseudogene regions. Gene is considered to have suboptimal coverage when >90% of the gene’s target nucleotides are not covered at >20x with mapping quality score (MQ>20) reads. The technology may have limited sensitivity to detect variants in genes marked with these symbols (please see the Panel content table above).

This test does not detect the following:
  • Complex inversions
  • Gene conversions
  • Balanced translocations
  • Mitochondrial DNA variants
  • Repeat expansion disorders unless specifically mentioned
  • Non-coding variants deeper than ±20 base pairs from exon-intron boundary unless otherwise indicated (please see above Panel Content / non-coding variants covered by the panel).
This test may not reliably detect the following:
  • Low level mosaicism (variant with a minor allele fraction of 14.6% is detected with 90% probability)
  • Stretches of mononucleotide repeats
  • Indels larger than 50bp
  • Single exon deletions or duplications
  • Variants within pseudogene regions/duplicated segments

The sensitivity of this test may be reduced if DNA is extracted by a laboratory other than Blueprint Genetics.

For additional information, please refer to the Test performance section and see our Analytic Validation.

The Blueprint Genetics retinal dystrophy panel covers classical genes associated with Bardet-Biedl syndrome, Alström syndrome, Joubert syndrome, Usher syndrome, Stickler syndrome, Norrie disease, Stargardt disease, x-linked retinoschisis, Cohen syndrome, Leber congenital amaurosis, retinal dystrophy, cone rod dystrophy, congenital stationary night blindness, achromatopsia, fundus albipunctatus, Senior-Loken syndrome, Refsum disease, retinitis pigmentosa, choroideremia, gyrate atrophy of choroid and retina and familial exudative vitreoretinopathy. The genes on the panel have been carefully selected based on scientific literature, mutation databases and our experience.

Our panels are sectioned from our high-quality, clinical grade NGS assay. Please see our sequencing and detection performance table for details regarding our ability to detect different types of alterations (Table).

Assays have been validated for various sample types including EDTA-blood, isolated DNA (excluding from formalin fixed paraffin embedded tissue), saliva and dry blood spots (filter cards). These sample types were selected in order to maximize the likelihood for high-quality DNA yield. The diagnostic yield varies depending on the assay used, referring healthcare professional, hospital and country. Plus analysis increases the likelihood of finding a genetic diagnosis for your patient, as large deletions and duplications cannot be detected using sequence analysis alone. Blueprint Genetics’ Plus Analysis is a combination of both sequencing and deletion/duplication (copy number variant (CNV)) analysis.

Bioinformatics

The target region for each gene includes coding exons and ±20 base pairs from the exon-intron boundary. In addition, the panel includes non-coding and regulatory variants if listed above (Non-coding variants covered by the panel). Some regions of the gene(s) may be removed from the panel if specifically mentioned in the ‘Test limitations” section above. The sequencing data generated in our laboratory is analyzed with our proprietary data analysis and annotation pipeline, integrating state-of-the art algorithms and industry-standard software solutions. Incorporation of rigorous quality control steps throughout the workflow of the pipeline ensures the consistency, validity and accuracy of results. Our pipeline is streamlined to maximize sensitivity without sacrificing specificity. We have incorporated a number of reference population databases and mutation databases including, but not limited, to 1000 Genomes Project, gnomAD, ClinVar and HGMD into our clinical interpretation software to make the process effective and efficient. For missense variants, in silico variant prediction tools such as  SIFT, PolyPhen, MutationTaster are used to assist with variant classification. Through our online ordering and statement reporting system, Nucleus, ordering providers have access to the details of the analysis, including patient specific sequencing metrics, a gene level coverage plot and a list of regions with <20X sequencing depth if applicable. This reflects our mission to build fully transparent diagnostics where ordering providers can easily visualize the crucial details of the analysis process.

Clinical interpretation

We provide customers with the most comprehensive clinical report available on the market. Clinical interpretation requires a fundamental understanding of clinical genetics and genetic principles. At Blueprint Genetics, our PhD molecular geneticists, medical geneticists and clinical consultants prepare the clinical statement together by evaluating the identified variants in the context of the phenotypic information provided in the requisition form. Our goal is to provide clinically meaningful statements that are understandable for all medical professionals regardless of whether they have formal training in genetics.

Variant classification is the corner stone of clinical interpretation and resulting patient management decisions. Our classifications follow the Blueprint Genetics Variant Classification Schemes based on the ACMG guideline 2015. Minor modifications were made to increase reproducibility of the variant classification and improve the clinical validity of the report. Our experience with tens of thousands of clinical cases analyzed at our laboratory allowed us to further develop the industry standard.

The final step in the analysis is orthogonal confirmation. Sequence variants classified as pathogenic, likely pathogenic and variants of uncertain significance (VUS) are confirmed using bi-directional Sanger sequencing when they do not meet our stringent NGS quality metrics for a true positive call.
Reported heterozygous and homo/hemizygous copy number variations with a size <10 and <3 target exons are confirmed by orthogonal methods such as qPCR if the specific CNV has been seen and confirmed less than three times at Blueprint Genetics.

Our clinical statement includes tables for sequencing and copy number variants that include basic variant information (genomic coordinates, HGVS nomenclature, zygosity, allele frequencies, in silico predictions, OMIM phenotypes and classification of the variant). In addition, the statement includes detailed descriptions of the variant, gene and phenotype(s) including the role of the specific gene in human disease, the mutation profile, information about the gene’s variation in population cohorts and detailed information about related phenotypes. We also provide links to the references, abstracts and variant databases used to help ordering providers further evaluate the reported findings if desired. The conclusion summarizes all of the existing information and provides our rationale for the classification of the variant.

Identification of pathogenic or likely pathogenic variants in dominant disorders or their combinations in different alleles in recessive disorders are considered molecular confirmation of the clinical diagnosis. In these cases, family member testing can be used for risk stratification. We do not recommend using variants of uncertain significance (VUS) for family member risk stratification or patient management. Genetic counseling is recommended.

Our interpretation team analyzes millions of variants from thousands of individuals with rare diseases. Our internal database and our understanding of variants and related phenotypes increases with every case analyzed. Our laboratory is therefore well-positioned to re-classify previously reported variants as new information becomes available. If a variant previously reported by Blueprint Genetics is re-classified, our laboratory will issue a follow-up statement to the original ordering health care provider at no additional cost.
