Genomic Counseling

Merogenomics Inc. recommends two genetic counseling sessions for clients who have their genomes sequenced. The first session should take place before the genome sequencing procedure; this session informs the client about the purpose of the test and its expectations. The second counseling session should follow the genome sequencing procedure and assists the client in interpreting the results of the test. 

 

Pretest Genetic Counseling

An important function of pretest genetic counseling is to prepare the client for the possibility of incidental findings in the genome sequence and the potential psychosocial impact of such findings. Pretest genetic counseling will entail a discussion of family medical history and disease inheritance (if applicable). The counselor will point out the limitations of the genome sequencing procedure, including error rates and the need for validation of any significant findings. The counselor will explain the significance of informed consent and describe how the results of sequencing can be used for diagnostic purposes for the benefit of the client and for research that could benefit the community.

 

Posttest Genetic Counseling

In posttest counseling, the client can expect an analysis and interpretation of any pathogenic results that might have been uncovered. Available management resources for individuals at risk of genetic disease (including access to support groups and educational material) will be proposed. A discussion of disease risk in the context of the subject’s immediate family (including the importance of sharing the results with at risk relatives) and the potential psychological implications of such disease risk will be undertaken. The potential impact of pathogenic variants (if they have been uncovered) on future reproductive decisions will be addressed.

Merogenomics Inc. can provide access to a genetic counselor for a fee.  

Counseling is provided by telephone or video; both methods have been shown to be practical alternatives to traditional face-to-face counseling. Counseling session is billed per one hour time slots.

 

Relationship Between Genetic Counselor and Physician

Genetic counseling is an independent service and is not included in what the ordering physician provides to the client. The ordering physician's role is to:

  • Properly accumulate evidence in favour of DNA testing, such as family and personal medical history, and then to order the test for the client by filling in and signing the test requisition form
  • Receive the DNA test results on behalf of the client/patient and deliver the results to the client/patient in the context of their medical history
  • Develop a medical management plan in the context of considering one’s existing medical history and their DNA test findings
  • Send the client/patient to a genetic counselor (if DNA testing is obtained privately outside of healthcare system, this option might not be available and the client/patient will have to seek independent access to genetic counseling)
  • Adapt a medical management plan based on the genetic counselor’s report

 

A genetic counselor will play very different role from the physician and will be able to address the DNA test results for the following purposes:

  • To inform the patient/client about the risk of disease development and potential outcomes, along with determining the risk of inheritance by future generations
  • Assess the proposed medical management by the ordering physician for an appropriate fit to a given condition

 

If pathogenic or likely pathogenic variants are reported to the physicians, all physicians should require their patients to see a genetic counselor. This is also true if a couple planning to have children discover they are carriers of mutations in the same genes which are linked to disease development.

Pharmacogenetic information might also need a genetic counselor’s oversight for certain niche medical specialties such as cancer, or neurological conditions.
