Comprehensive Skeletal / Malformation Syndrome Panel

  • bpg-method PLUS
  • bpg-method SEQ
  • bpg-method DEL/DUP

Test code: MA3201

The Blueprint Genetics Comprehensive Skeletal / Malformation Syndrome Panel is a 429 gene panel. This panel covers vast majority of the genes listed in the Nosology 2015 (PMID: 26394607) and all genes in the category (Malformations) therefore providing maximal differential diagnostic power in the field.

This panel is ideal for:

  • Patients suspected to have a malformation syndrome
  • Patients suspected to have a skeletal dysplasia

Due to one or more regions of segmental duplication, this panel has reduced sensitivity to detect variants in regions of 34 of the 429 genes on this panel (for a complete list of the affected genes, please refer to the Gene Set Description list for this panel). This is not suspected to significantly decrease the sensitivity of the panel overall. If you suspect one of the affected genes is responsible for the phenotype in your patient, please contact our Support Team for additional information.

This comprehensive panel consists of 32 unique subpanels including 429 unique genes and provides maximal differential diagnostic power for these patients.

Blueprint Genetics (BpG) offers comprehensive genetic diagnostics for malformations. In total the malformation category consists of 32 unique panels including 429 unique genes, all covered by this comprehensive panel. Inherited skeletal diseases are known to be difficult to subtype and divide to categories. This panel covers vast majority of the genes listed in the Nosology 2015 (PMID: 26394607) and all genes in the category (Malformations) therefore providing maximal differential diagnostic power in the field.

About Malformation Syndromes

This panel covers broad spectrum of connective tissue and skeletal disorders leading to syndromes manifesting from isolated defects, growth abnormalities to malformations in the whole body level. Some of the panels cover organ specific malformations such as Hirschsprung disease and gastrointestinal atresias, cerebral cavernous malformations and neurofibromatosis. Genetic diagnostics in these diseases is the most efficient way to subtype the diseases and enable individualized treatment and management decisions. Moreover, detection of causative mutation establishes inheritance mode of the disease in the family which is essential for informed genetic counseling.

Availability

Results in 3-4 weeks. We do not offer a maternal cell contamination (MCC) test at the moment. We offer prenatal testing only for cases where the maternal cell contamination studies (MCC) are done by a local genetic laboratory. Read more: http://blueprintgenetics.com/faqs/#prenatal

The strengths of this test include:

  • Blueprint Genetics is one of the few laboratories worldwide with CAP and ISO-15189 accreditation for NGS panels and CLIA certification
  • Superior sequencing quality
  • Careful selection of genes based on current literature, our experience and the most current mutation databases
  • Transparent and easy access to quality and performance data at the patient level that are accessible via our Nucleus portal
  • Transparent and reproducible analytical validation for each panel (see Test performance section; for complete details, see our Analytic Validation)
  • Sequencing and high resolution del/dup analysis available in one test
  • Inclusion of non-coding disease causing variants where clinically indicated (please see individual Panel descriptions)
  • Interpretation of variants following ACMG variant classification guidelines
  • Comprehensive clinical statement co-written by a PhD geneticist and a clinician specialist

This test does not detect the following:

  • Sequence variants located in the PTEN promoter region with the exception of c.-862G>T, c.-765G>A or those in close proximity
  • Complex inversions
  • Gene conversions
  • Balanced translocations
  • Mitochondrial DNA variants
  • Variants in regulatory or non-coding regions of the gene unless otherwise indicated (please see Non-coding disease causing variants covered by the panel). This mean for instance intronic variants locating deeper than 15 nucleotides from the exon-intron boundary.

 

This test may not reliably detect the following:

  • Low level mosaicism
  • Stretches of mononucleotide repeats
  • Indels larger than 50bp
  • Single exon deletions or duplications
  • Variants within pseudogene regions/duplicated segments
  • Disorders caused by long repetitive sequences (e.g. trinucleotide repeat expansions)

 

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.

Blueprint Genetics offers a Comprehensive Skeletal / Malformation Syndrome Panel that covers classical genes associated with malformations and skeletal syndromes. The genes are carefully selected based on the existing scientific evidence, our experience and most current mutation databases. Candidate genes are excluded from this first-line diagnostic test. The test does not recognise balanced translocations or complex inversions, and it may not detect low-level mosaicism. The test should not be used for analysis of sequence repeats or for diagnosis of disorders caused by mutations in the mitochondrial DNA.

Analytical validation is a continuous process at Blueprint Genetics. Our mission is to improve the quality of the sequencing process and each modification is followed by our standardized validation process. Average sensitivity and specificity in Blueprint NGS Panels is 99.3% and 99.9% for detecting SNPs. Sensitivity to for indels vary depending on the size of the alteration: 1-10bps (96.0%), 11-20 bps (88.4%) and 21-30 bps (66.7%). The longest detected indel was 46 bps by sequence analysis. Detection limit for Del/Dup (CNV) analysis varies through the genome depending on exon size, sequencing coverage and sequence content. The sensitivity is 71.5% for single exon deletions and duplications and 99% for three exons’ deletions and duplications. We have validated the assays for different starting materials including EDTA-blood, isolated DNA (no FFPE) and saliva that all provide high-quality results. The diagnostic yield varies substantially depending on the used assay, referring healthcare professional, hospital and country. Blueprint Genetics’ Plus Analysis (Seq+Del/Dup) maximizes the chance to find molecular genetic diagnosis for your patient although Sequence Analysis or Del/Dup Analysis may be cost-effective first line test if your patient’s phenotype is suggestive for a specific mutation profile.

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. The highest relevance in the reported variants is achieved through elimination of false positive findings based on variability data for thousands of publicly available human reference sequences and validation against our in-house curated mutation database as well as the most current and relevant human mutation databases. Reference databases currently used are the 1000 Genomes Project (http://www.1000genomes.org), the NHLBI GO Exome Sequencing Project (ESP; http://evs.gs.washington.edu/EVS), the Exome Aggregation Consortium (ExAC; http://exac.broadinstitute.org), ClinVar database of genotype-phenotype associations (http://www.ncbi.nlm.nih.gov/clinvar) and the Human Gene Mutation Database (http://www.hgmd.cf.ac.uk). The consequence of variants in coding and splice regions are estimated using the following in silico variant prediction tools: SIFT (http://sift.jcvi.org), Polyphen (http://genetics.bwh.harvard.edu/pph2/), and Mutation Taster (http://www.mutationtaster.org).

Through our online ordering and statement reporting system, Nucleus, the customer can access specific details of the analysis of the patient. This includes coverage and quality specifications and other relevant information on the analysis. This represents our mission to build fully transparent diagnostics where the customer gains easy access to crucial details of the analysis process.

In addition to our cutting-edge patented sequencing technology and proprietary bioinformatics pipeline, we also provide the customers with the best-informed clinical report on the market. Clinical interpretation requires fundamental clinical and genetic understanding. At Blueprint Genetics our geneticists and clinicians, who together evaluate the results from the sequence analysis pipeline in the context of phenotype information provided in the requisition form, prepare the clinical statement. Our goal is to provide clinically meaningful statements that are understandable for all medical professionals, even without training in genetics.

Variants reported in the statement are always classified using the Blueprint Genetics Variant Classification Scheme modified from the ACMG guidelines (Richards et al. 2015), which has been developed by evaluating existing literature, databases and with thousands of clinical cases analyzed in our laboratory. Variant classification forms the corner stone of clinical interpretation and following patient management decisions. Our statement also includes allele frequencies in reference populations and in silico predictions. We also provide PubMed IDs to the articles or submission numbers to public databases that have been used in the interpretation of the detected variants. In our conclusion, we summarize all the existing information and provide our rationale for the classification of the variant.

A final component of the analysis is the Sanger confirmation of the variants classified as likely pathogenic or pathogenic. This does not only bring confidence to the results obtained by our NGS solution but establishes the mutation specific test for family members. Sanger sequencing is also used occasionally with other variants reported in the statement. In the case of variant of uncertain significance (VUS) we do not recommend risk stratification based on the genetic finding. Furthermore, in the case VUS we do not recommend use of genetic information in patient management or genetic counseling. For some cases Blueprint Genetics offers a special free of charge service to investigate the role of identified VUS.

We constantly follow genetic literature adapting new relevant information and findings to our diagnostics. Relevant novel discoveries can be rapidly translated and adopted into our diagnostics without delay. These processes ensure that our diagnostic panels and clinical statements remain the most up-to-date on the market.
