Clinical Utility of Mate Pair Sequencing
Hosted by Mayo Clinic
About this course
Genomic case conferences are on-demand webinars that focus on the adaptation of exome or genome sequencing technology in clinical care. During the ACMG Genomics Case Conferences, expert(s) from select institutions will present and lead discussions on an intriguing, complex and/or difficult patient cases in the area of genomics. Genomic Case Conferences are free for Members/Trainees (credits not included).

Session Description:
For many decades chromosome studies were the gold standard of cytogenetic testing for patients with abnormal congenital phenotypes. Chromosomal microarray (CMA) has replaced karyotype as a first-tier test for these patients; however, chromosome studies are still utilized to some degree, particularly following a normal microarray study. Chromosome studies have the ability to detect apparently balanced rearrangements such as translocation, but without a molecular understanding of the breakpoints of the rearrangement in question, those findings most often have uncertain clinical significance. Similarly, CMA studies frequently detect copy number gains with breakpoint boundaries that may or may not disrupt genes associated with an abnormal phenotype resulting from haploinsufficiency. Parental testing to distinguish inherited from de novo events is recommended in these scenarios; however, patients are still frequently left with results of uncertain clinical significance. Mate pair sequencing (MPseq) has been shown to be a useful strategy to characterize such rearrangements, providing clarity to the significance of such rearrangements in many cases. This session will explain how MPseq works, describe situations in which this assay is useful, and summarize the clinical experience of this assay to date with respect to sensitivity and success rate with respect to re-classifying variants of uncertain significance.

Learning objectives

At the conclusion of the series, participants should be able to:

  1. Describe the clinical utility of whole exome/whole genome sequencing tests
  2. Identify clinical indications for whole exome/whole genome sequencing
  3. List determinants used to assess the probability of a variant’s pathogenicity
  4. Elaborate on the importance of pre-test counseling and consent

 

Session learning objectives

At the conclusion of this session, participants should be able to:

  1. Discuss the current gaps that exist in clinical cytogenetic testing
  2. Describe how mate pair sequencing works and how it differs from other forms of whole genome sequencing
  3. Identify situations in which mate pair sequencing can be used to aid in the interpretation of results of uncertain clinical significance

 

Continuing Education Information:

CONTINUING MEDICAL EDUCATION (CME)

The American College of Medical Genetics and Genomics is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to provide continuing medical education for physicians.

Credit Designation:

The American College of Medical Genetics and Genomics designates this enduring activity for a maximum of 1 AMA PRA Category 1 Credits™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

CONTENT VALIDATION AND FAIR BALANCE

ACMG follows the ACCME policy on Content Validation for CME activities, which requires: a)All recommendations involving clinical medicine must be based on evidence that is accepted within the profession of medicine as adequate justification for their indications and contraindications in the care of patients. b)  All scientific research referred to, reported or used in CME in support or justification of patient care recommendations must conform to the generally accepted standards of experimental design, data collection and analysis. Activities that fall outside the definition of CME/CE; “Educational activities that serve to maintain, develop, or increase the knowledge, skills, and professional performance and relationships that a physician uses to provide services for patients, the public, or the profession” (source: ACCME and AMA) will not be certified for credit. CME activities that promote recommendations, treatment, or manners of practicing medicine or pharmacy that are not within the definition of CME/CE or, are known to have risks or dangers that outweigh the benefits or, are known to be ineffective in the treatment of patients. Presentations and CME/CE activity materials must give a balanced view of therapeutic options; use of generic names will contribute to this impartiality.  If the CME/CE educational materials or content includes trade names, where available, trade names from several companies must be used.

HIPAA COMPLIANCE BY FACULTY

The ACMG supports medical information privacy. While the ACMG is not a “covered entity” under HIPAA 1996 and therefore is not required to meet these standards, ACMG wishes to take reasonable steps to ensure that the presentation of individually identifiable health information at ACMG-sponsored events has been properly authorized. All presenters have completed a form indicating whether they intend to present any form of individually identifiable healthcare information. If so, they were asked either to attest that a HIPAA-compliant consent form is on file at their institution, or to send ACMG a copy of the ACMG HIPAA compliance form. This information is on record at the ACMG Administrative Office and will be made available upon request.
