Children & Adults 

 
Family physicians or other medical specialists refer families for a medical genetics consultation for some of these reasons:
  • Families in which one or more members have a serious birth defect or genetic disease
  • Families who have a child with multiple congenital anomalies, serious developmental delay, or an unexplained abnormality of growth
  • Families in which more than one close relative has the same disease (e.g., mental retardation, deafness, blindness, cancer, early heart attacks, or schizophrenia)
  • Couples who have had repeated stillbirths or a stillborn baby with birth defects
  • Couples who are close blood relatives (e.g., first cousins)
To make a referral, please ensure your physician completes the appropriate form located on the page Contact Us/Making a Referral.

What Happens in a Genetics Consultation?

Genetics consultations usually involve one or more in-person visits and phone calls with genetic care providers.

Who Provides Genetics Consultations?

Trained genetic practitioners include medical geneticists and genetic counsellors. Patients may be seen independently by a genetic counsellor, but in cases where a diagnosis needs to be established, a medical geneticist must be directly involved. A genetic consultation will include some of the following steps:

Assessment: Gathering information
  • Explore with the patient and family:
    • Reason for referral
    • Understanding of genetics
    • Diagnoses under consideration
    • Perception of disease status or risk
    • Beliefs about cause of disease
    • Perception of disease burden
    • Document patient's birth history, past medical history and current status.
  • Obtain directed family history in pedigree form using standing symbols, including:
    • The patient's first degree (children, siblings, parents) and second degree (grandparents, grandchildren, aunts, uncles, nieces, nephews) relatives, and further removed as appropriate
    • Status of current pregnancies
    • Ethnic background
    • Presence of consanguinity
  • Obtain and review additional medical records, including diagnostic testing, on patient and affected family member(s) as needed.
  • Review the family's social history, education, employment and social functioning.
  • Assess the family's sources of psychosocial support (community, religious, family).
  • Identify potential ethical issues such as confidentiality, insurability, discrimination and non-paternity.
  • Perform physical examination of the patient and other family members as needed.
Evaluation: Interpreting the medical and family history and the results of the physical examination and tests
  • Consult relevant references.
  • Compare patient's history and exam to known diagnoses.
  • Discuss diagnostic impression.
  • Clear diagnosis - Share information about the condition
  • Differential diagnosis - Suggest further tests or evaluations
  • Unknown diagnosis - Discuss what known diagnoses are ruled out and follow over time
Communication: Sharing information about the condition
  • Review the details about the disorder in question including:
    • Expected course of the disease
    • Management issues, and possible treatments or interventions
    • Underlying genetic cause if known, including pattern of inheritance
  • Describe risks to family members compared with general population risks.
  • Discuss reproductive options, if and when appropriate, which may include:
    • Pregnancy with prenatal testing
    • Pregnancy without prenatal testing
    • Remaining childless
    • Parenting by adoption
    • Pregnancy by egg or sperm donation
    • Pregnancy following pre-implantation genetic diagnosis
Support: Helping the family cope
  • Recognize and discuss the emotional responses of family members to information given (which may include shock, disbelief, relief, fear, guilt, sadness, shame, and acceptance).
  • Review normal grief responses and signs that might indicate the need for further psychosocial support.
  • Listen to the whole story, and hear what this situation has meant to the family.
  • Explore strategies for communicating information to others, especially family members who may be at risk.
  • Provide written materials and referrals to support groups, other families with the same or similar condition, and local and national service agencies.
Follow-up: Maintaining ongoing communication
  • Arrange for follow-up diagnostic testing or management appointments, or communicate this need to the referring healthcare provider.
  • Document the content of the consultation for the referring health care provider and for the patient when appropriate.
  • Contact the patient to assess level of understanding and response to decisions made.
  • Encourage family to contact the clinic when considering pregnancy or for updated information.
  • Be available to answer future questions.
