Test Description

PMC Chronic Pancreatitis (CP) Panel examines genes linked to CP| a condition that causes permanent changes in the pancreas and affects both exocrine and endocrine functions. Using a broad panel for testing can efficiently assess multiple genes for individuals with similar clinical symptoms.

  • Methodology

    Targeted Exome/ Slice Exome (Next Generation Sequencing including Copy Number Variation)

  • Assay Information
    • CFTR: Analysis includes the intronic variants: NM_000492.3:c.3718-2477C >T (also known as 3849+10kbC >T)| c.1210-34TG13T5 (also known as T5TG13)| c.1210-34TG12T5 (also known as T5TG12)| c.1210-34TG11T5 (also known as T5TG11)| and c.1679+1634A >G. Sequencing analysis for exons 7 includes only cds +/- 10 bp.
    • PRSS1: Sequencing analysis for exons 4 includes only cds +/- 10 bp.
  • Limitations

    All sequencing technologies have limitations. A negative result from this analysis does not rule out a possible genetic diagnosis as some variants may not be detected by this test. This test is not designed to detect low level mosaicism, structural rearrangements, indels >40bp, deep intronic variants of unknown clinical significance, or large cytogenetic CNVs. Certain inherent qualities of the human genome, for example repetitive regions/homopolymers, GC rich, pseudogenes, and rare polymorphisms, pose significant technical challenges such as sequence misalignment that may potentially impact the accuracy of the results. False negative results may also occur in the setting of allogeneic bone marrow, stem cell transplantation, active or chronic hematologic conditions, recent blood transfusions, suboptimal DNA quality or PCR trace contamination. Other potential sources of error include sample mix-ups and clerical issues.
