The identification of recurrent gene rearrangements in the clinical laboratory is the cornerstone for risk stratification and treatment decisions in many malignant tumors. Studies have reported that targeted next-generation sequencing assays have the potential to identify such rearrangements; however, their utility in the clinical laboratory is unknown. We(More)
As controversy exists regarding the prognostic significance of genomic rearrangements of CRLF2 in pediatric B-precursor acute lymphoblastic leukemia (ALL) classified as standard/intermediate-risk (SR) or high-risk (HR), we assessed the prognostic significance of CRLF2 mRNA expression, CRLF2 genomic lesions (IGH@-CRLF2, P2RY8-CRLF2, CRLF2 F232C),(More)
In cancer medicine, next generation sequencing (NGS) has emerged as a practical method to generate patient- and tumor-specific genetic data for optimal selection of targeted therapies. Targeted sequencing allows clinical testing to focus on cancer-related genes, thus maximizing the test's sensitivity and specificity for actionable variants. In this review,(More)
The use of NextGen Sequencing clinically necessitates the need for informatics tools that support the complete workflow from sample accessioning to data analysis and reporting. To address this need we have developed Clinical Genomicist Workstation (CGW). CGW is a secure, n-tiered application where web browser submits requests to application servers that(More)
Currently, oncology testing includes molecular studies and cytogenetic analysis to detect genetic aberrations of clinical significance. Next-generation sequencing (NGS) allows rapid analysis of multiple genes for clinically actionable somatic variants. The WUCaMP assay uses targeted capture for NGS analysis of 25 cancer-associated genes to detect mutations(More)
Array comparative genomic hybridization has increasingly become the standard of care to evaluate patients for genomic imbalance. As the patient population evaluated by microarray expands, there is certain to be an increase in the detection of unexpected, yet common diseases. When array results predict a late-onset disorder or cancer predisposition, it(More)
Structural and sequence variation have been described in several members of the contactin (CNTN) and contactin-associated protein (CNTNAP) gene families in association with neurodevelopmental disorders, including autism. Using array comparative genome hybridization (CGH), we identified a maternally inherited ∼535 kb deletion at 3p26.3 encompassing the 5'(More)
The limb-girdle muscular dystrophies (LGMDs) are a heterogenous group of diseases characterized by shoulder-girdle and pelvic muscle weakness and wasting. LGMD 2E is an autosomal recessively inherited form of the disease caused by mutations in the β-sarcoglycan (SGCB) gene located at 4q12. In this report, we describe a patient who demonstrates non-Mendelian(More)
BACKGROUND A clinical assay was implemented to perform next-generation sequencing (NGS) of genes commonly mutated in multiple cancer types. This report describes the feasibility and diagnostic yield of this assay in 381 consecutive patients with non-small cell lung cancer (NSCLC). METHODS Clinical targeted sequencing of 23 genes was performed with DNA(More)
Precision medicine uses individually determined genomic information to guide treatment in cancer and other diseases. We have implemented a clinical genomics assay that uses targeted next-generation sequencing of 25 cancer-related genes to guide the use of targeted therapies in diverse malignancies. We report the case of a 55-year-old woman with a poorly(More)
