Before You Arrive: Preparing Without Pressure
Bring any relevant medical documents — test results, imaging reports, or family members’ genetic reports if available.
Prepare a three-generation family health history: your own generation, your parents and their siblings, and both sets of grandparents.
For each person, useful information includes: age, health conditions, age of diagnosis, and if deceased, age and cause of death.
An incomplete family history is not a barrier — genetic counsellors are trained to work with uncertainty. Share whatever you know.
Inside the Room: Safety Before Information
The session begins not with reports or questions, but with building a safe, unhurried space.
Yoyo introduces herself, then invites the client to speak first: “What brought you here today?” or “What would you like to take away from this session?”
There are no wrong answers. Expressing fear, confusion, or simply saying “my doctor sent me” are all equally valid starting points.
Drawing the Family Tree (Pedigree)
A pedigree is a standardised, symbol-based diagram mapping three generations of health history.
It functions as a detective’s map — helping identify whether a disease is an isolated occurrence or part of an inherited pattern.
Clients are encouraged to mention even seemingly minor details, such as an uncle who had an unexplained operation, or a relative diagnosed at an unusually young age — these often become the most important clues.
Understanding Testing & Decoding a Report
People typically come for one of two reasons: deciding whether to pursue genetic testing, or needing help understanding an existing report.
For those considering testing: Yoyo discusses the rationale, benefits, risks, and limitations. Not every test guarantees a clear answer — understanding what a test cannot tell you is part of informed consent.
For those with an existing report: Yoyo translates and contextualises the findings, including which genes were tested and what any variants mean.
Variant classifications explained:
Pathogenic / Likely Pathogenic — sufficient evidence of disease association.
VUS (Variant of Uncertain Significance) — insufficient current data to determine impact; a dedicated future episode will explore this further.
Benign — not considered clinically significant.
A “positive” result is not a verdict — it is a piece of intelligence to be understood and acted upon thoughtfully.
Exploring Options & Respecting Personal Values
Genetic counselling is grounded in informed, autonomous decision-making. Yoyo does not tell clients what to do.
All reasonable options are laid out, with their benefits, risks, and trade-offs clearly explained.
For example, a hereditary cancer risk may involve options such as enhanced surveillance, preventive medication, or prophylactic surgery.
The “right” choice depends entirely on the individual’s values, life stage, and risk tolerance. All personal considerations are valid.
Making Room for Emotion
Many clients arrive carrying fear, grief, or guilt — including worries about having passed something harmful to their children.
Crying during a session is completely normal, as is going blank and forgetting what was just discussed.
Genetic counsellors are trained to hold space for emotional responses — their care extends beyond a client’s DNA to the whole person.
Wrapping Up: Next Steps & the Written Report
Sessions run approximately 45 minutes to 1 hour depending on complexity.
The session closes with a clear, jointly agreed action plan, which may include further testing, specialist referrals, recommendations for family members, or a follow-up session.
Before leaving, clients are asked: “Is there anything we haven’t covered that you’d like to know before you go?”
A written summary letter is sent to the client afterwards, documenting the family history, risk assessment, and recommended next steps — so there is no need to memorise anything during the session.
Closing Thought
Genetic counselling is not a diagnosis, and not a verdict — it is a guided process that helps you understand your genetic information and reclaim your sense of agency.
