Clinical validity: Help
Samples from eighteen patient cases from the Metabolic Hematology laboratory that had other clinical testing results (CE, HPLC, RBC enzyme levels, morphology) used to diagnose the patient were sequenced. The data for all patient cases revealed reportable sequence alterations in genes associated with the patient's phenotype and diganosis. All variants … View more

Target population: Help
Patients with a personal or family history suggestive of hereditary hemolytic anemias, including RBC membrane disorders and RBC enzymopathies.
Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
All detected variants are evaluated according to the most recent American College of Medical Genetics and Genomics (ACMG) and Association for Molecular Pathology (AMP) recommendations. Variants are classified based on known, predicted, or possible pathogenicity and reported with interpretive comments detailing their potential or known significance.

Are family members with defined clinical status recruited to assess significance of VUS without charge? Help
Decline to answer.

Will the lab re-contact the ordering physician if variant interpretation changes? Help
No. The laboratory encourages health care providers to contact the laboratory at any time to learn how the status of a particular variant may have changed over time.

Technical Information
Test Procedure: Help
Next-generation sequencing (NGS) is performed using the Illumina MiSeq or HiSeq instrument with paired-end, 151-base pair (bp) reads. The DNA is prepared for NGS using a custom Agilent SureSelect Target Enrichment System. Data is analyzed with the CLC Genomics Server Program. Supplemental or confirmatory Sanger sequencing is performed when necessary … View more
Test Confirmation: Help

Entire test performed in-house
Analytical Validity: Help
Fifteen samples with 30 previously described and/or reported sequencing results were tested and this assay confirmed all previously reported sequence variants with 100% accuracy using the MiSeq and orthogonal confirmatory testing method. Additionally, a variant list generated using the GeT-RM Browser on the NCBI website for two well characterized HapMap … View more
Assay limitations: Help
This assay is not intended to detect large deletions at this time. During verification, this assay accurately detected both a 25bp and 44bp deletion in the HBB. However, all suspected large deletions will be confirmed using another validated method.
