Hematologic Malignancy Comprehensive Panel

Test results and variant interpretation are based on the proper identification of the submitted specimen and use of correct human reference sequences at the queried loci. In very rare instances, errors may result due to mix-up or co-mingling of specimens. Positive results do not imply that there are no other contributions, genetic or otherwise, to the patient’s phenotype, and negative results do not rule out a genetic cause for the indication for testing. Official gene names change over time. Fulgent uses the most up to date gene names based on HUGO Gene Nomenclature Committee (https://www.genenames.org) recommendations. If the gene name on report does not match that of ordered gene, please contact the laboratory and details can be provided. Result interpretation is based on the collected information and Alamut annotation available at the time of reporting. This assay is not designed or validated for the detection of mosaicism. DNA alterations in regulatory regions or deep intronic regions (greater than 20bp from an exon) will not be detected by this test. There are technical limitations on the ability of DNA sequencing to detect small insertions and deletions. Our laboratory uses a sensitive detection algorithm, however these types of alterations are not detected as reliably as single nucleotide variants. Rarely, due to systematic chemical, computational, or human error, DNA variants may be missed. Although next generation sequencing technologies and our bioinformatics analysis significantly reduce the confounding contribution of pseudogene sequences or other highly-homologous sequences, sometimes these may still interfere with the technical ability of the assay to identify pathogenic variant alleles in both sequencing and deletion/duplication analyses. Deletion/duplication analysis can identify alterations in genomic regions and is evaluated at a single exon resolution level in relevant genes associated with the patient’s clinical presentation. For custom added genes and applicable genes that may be of interest, deletion/duplication analysis is evaluated at a resolution of two or more contiguous exons. When novel DNA duplications are identified, it is not possible to discern the genomic location or orientation of the duplicated segment, hence the effect of the duplication cannot be predicted. Where deletions are detected, it is not always possible to determine whether the predicted product will remain in-frame or not. Unless otherwise indicated, in regions that have been sequenced by Sanger, deletion/duplication analysis has not been performed. Patients with Bone Marrow Transplants: DNA extracted from cultured fibroblasts should be submitted instead of blood/saliva/buccal samples from individuals who have undergone allogeneic bone marrow transplant and from patients with hematologic malignancy.
