PPM – Chromosome and FISH Analyses of Patients with Suspicion of Turner Syndrome
Version 2021

Chromosome and FISH Analyses of Patients with Suspicion of Turner Syndrome

Version: July 2021



This module is an overview of recommendations for metaphase chromosome analysis, with possible additional FISH, for patients suspected of having Turner syndrome.  This module does not address primary assessment by chromosomal microarray. Laboratory Directors are asked to choose 5 consecutive cases, including prenatal and postnatal specimens, with an indication of possible Turner syndrome that were most recently signed out in your laboratory.  For each case, answer the following 17 questions regarding the work-up of the cases.  Answer choices will be yes, no or not-applicable.  At the end of the activity, you will be asked four questions assessing your performance on this module.

Practice Performance Modules (CCP Part IV)

(Continuing Certification Program was formerly the Maintenance of Certification Program (MOC)

Practice performance modules are derived from accepted practice guidelines related to genetics patient care. Modules are available for pediatric genetics, adult genetics and prenatal/obstetric genetic care providers.


  1. Educational Content – Review module, literature, and practice checklist
  2. Charting – Each module requires the learner to review up to 5 patient charts and documenting certain findings according to the module questions.
  3. Assessment and Self-reflection Questions
  4. Evaluation

Completion of these modules should be based on actual patient care as documented in your patient chart. The process is not meant to be punitive but designed to help assess practice and facilitate practice improvement. The modules should be completed honestly based on documentation in the chart. An audit process may be implemented by ACMG to document compliance. Learners should keep track of the specific charts used to complete the practice module so that these charts could be reproduced in the setting of an audit.

Self-reflections should be meaningful and provide evidence that the diplomate has considered the practice guidelines contained in the exercise in the context of their own clinical practice. Answers to reflection questions should be 2-3 full sentences long and have thoughtful content. Answers to reflection questions will be anonymized and reviewed for content by the MOC committee. Reflections that do not meet these guidelines will be returned to the diplomate for revision. Revisions that do not meet guidelines may result in forfeiture of MOC credit for a given module and a request to repeat the module.

  1. Do you think this module reflects best practice?  Please elaborate whether you agree or disagree and state why.
  2. Did you identify any gaps in your practice?  If so, please elaborate.
  3. If you identified gaps in your practice, what changes do you plan make to your practice based on this module?

What if any barriers do you foresee for implementing change if you identified gaps in your practice? For example, short staffing, time factors etc.
