Genetic counselling is a specialised healthcare service that helps individuals understand how genetic conditions might affect them and their families. Genetic counsellors provide medical insights and psychological support while navigating complex genetic information and diagnosis. This service further identifies family members who may be at risk of inheriting a genetic condition by assessing their likelihood or probability and recommending genetic testing if needed.
These services are provided by professional genetic counsellors who thoroughly review personal and family medical histories and guide patients through complex genetic information and potential health implications. They help select and interpret appropriate genetic tests, such as diagnostic testing, carrier screening, prenatal testing, predictive testing, newborn screening and risk assessments testing, which support informed healthcare decision-making.
Genetic counselling services cover diverse areas including prenatal care, cancers, paediatric and adult genetic diseases, and reproductive health, addressing a wide range of common and rare genetic conditions.
Why is Genetic Counselling Important in Rare Disease?
As rare diseases affect small numbers of people, there is often limited knowledge about them. When someone is diagnosed with a rare disease, both the individual and their family need help to understand the genetics behind the condition and how to cope with the psychosocial challenges like anger, anxiety, depression and fear of genetic discrimination. Genetic counselling offers this vital support.
Genetic counsellors guide patients through the diagnostic journey by providing comprehensive risk assessment, interpreting family histories, coordinating genetic testing with laboratories, and collaborating with physicians to help establish accurate genetic diagnosis.
During the diagnostic journey and after receiving a genetic diagnosis, genetic counsellors provide education and help families navigate connections with appropriate specialists, ensuring they have the understanding and support needed to manage their rare disease effectively.
Who Are Genetic Counsellors?
Genetic counsellors are highly trained professionals with a Master of Science degree in genetic counselling. They have advanced expertise in medical genetics and in providing emotional and psychological support; addressing both psychological (e.g emotional issues) and social (e.g supporting family communication) aspects of genetic diagnosis. This allows them to guide patients in understanding genetic conditions, interpreting genetic test results, and managing related challenges such as communicating complex genetic information, addressing emotional concerns and supporting families through decision-making and risk assessment processes. Their training combines rigorous theoretical and practical sessions, preparing them to address the complexities of genetic conditions in healthcare. After earning their degree, they obtain professional licensing to practice. This blend of medical and counselling skills makes genetic counsellors uniquely qualified to support patients and families through genetic diagnosis and management.
While genetic counselling is primarily provided by Master’s-trained, board-certified genetic counsellors, the specific practitioners may vary by country and healthcare system.
The Role of a Genetic Counsellor
-
Genetic testing and diagnosis
Diagnosing a rare disease is often a lengthy process, which sometimes takes years to confirm. While modern genetic testing methods have improved diagnostic outcomes, limitations in these technologies often require the expertise of genetic counsellors. Genetic counsellors help navigate these challenges, including ethical concerns and secondary findings that can complicate diagnoses.
Genetic counsellors work closely with physicians to analyse family histories and assess genetic risks, while also providing guidance on selecting and interpreting appropriate genetic tests. This collaborative approach helps physicians reach accurate diagnoses more efficiently. Acting as liaisons between families and genetic laboratories, genetic counsellors oversee test selection and results interpretation, ensuring clear communication and relieving families of this burden.
This additional expertise offered by genetic counsellors shortens the diagnostic process, reduces clinical costs, and reduces the stress experienced by patients and families.
-
Education and support
Understanding a rare disease is an important step in managing it effectively. Genetic counsellors provide individuals and families with detailed clinical and genetic information tailored to their needs while respecting their values, religious beliefs, and cultural background. They simplify complex genetic concepts into easy-to-understand language, ensuring accessibility for people of all literacy levels.
Recognising that genetic diagnoses can be overwhelming, genetic counsellors also offer emotional support to help patients and families cope. They use strategies like active listening, validation of feelings, connecting families with support networks, and helping patients develop coping skills to navigate the emotional challenges of their genetic diagnosis. During sessions, they assess psychological needs and provide customised support.
They refer families to appropriate resources and services based on their specific circumstances. These resources include support groups, educational materials and specialist clinics that address the specific needs of families.

Inheritance risk and Family planning guidance
Family history is a crucial tool in genetic counselling for assessing genetic risks. Since genetic conditions often affect families, counselling helps assess the risks for other family members and determine whether the condition might be inherited. Many rare diseases occur by chance (de novo), meaning the individual is the first member affected in their family. However, some rare diseases are inherited. In these cases, relatives who may be carriers of the condition (meaning they carry a single copy of a gene mutation for a recessive condition without showing symptoms) can benefit from genetic counselling. Counselling can help them understand their risks, explore reproductive options, and plan for future pregnancies to reduce the chance of having an affected child.
Genetic counsellors provide guidance on reproductive options to help families reduce the risk of passing on genetic conditions. These options include prenatal testing to check for genetic conditions in an unborn child or pre implantation genetic testing, which ensures only embryos free of specific genetic conditions are implanted.
By understanding inheritance risks and reproductive options, families can make informed decisions to minimise the likelihood of passing on genetic conditions. Genetic counsellors play a central role in this process, helping to decrease the occurrence of certain inherited conditions within families through education and support.
Genetic Counsellors in Rare Disease Management
Understanding the details of a rare disease is essential for families to manage their condition effectively. Genetic counsellors provide in-depth information about the genetic basis of rare diseases and connect patients with support groups, specialised healthcare providers, and clinical trials. Support groups help families adapt to their diagnosis, while clinical trials introduce them to emerging treatment options.
Genetic counsellors guide families to specialised care providers, ensuring they receive targeted medical attention. They also help individuals at risk of passing on inherited conditions explore reproductive options, such as pre implantation genetic testing during in-vitro fertilisation (IVF), to reduce the likelihood of having affected children.
By identifying at-risk family members, genetic counsellors facilitate sessions to address their concerns. Additionally, knowledge of a condition’s genetic basis allows counsellors to collaborate with healthcare teams, tailoring treatment and management plans to align with the patient’s unique genetic profile while incorporating the latest advances in research.
When to See a Genetic Counsellor
If symptoms of a genetic condition appear or a clinician diagnoses a genetic disease, a genetic counsellor can help families understand the condition, its implications, and management options.
For those with a family history of genetic conditions who are planning to have children, genetic counselling is essential. Counsellors assess risks, recommend appropriate genetic tests, and explain reproductive options to reduce the likelihood of passing on the condition.
Relatives of someone diagnosed with a genetic condition can also benefit from genetic counselling to understand their own risks of developing or passing on the condition.
In summary, you should consider genetic counselling in these scenarios:
-
You have a family history of a genetic condition.
-
You are planning a pregnancy and want carrier screening.
-
You have symptoms of an unclear or undiagnosed condition.
-
You wish to proactively understand your genetic health risks.
-
You were recently diagnosed with a genetic condition and need guidance.
-
You are adopted and want to learn about potential genetic risks.
What to Expect in a Genetic Counselling Session
A genetic counselling session typically begins with the counsellor asking about the family’s concerns and what they hope to learn. This empowers families to voice their knowledge gaps and set goals for the session. The counsellor then collects detailed information about the family’s medical history and any known health conditions, using this information to create a family tree.
The genetic counsellor analyses the family and medical history to assess the risks of genetic conditions within the family. They explain the condition, including its symptoms, management options, genetic basis, inheritance patterns, and how the genetic change may have occurred. Throughout the session, the counsellor encourages questions and provides clear explanations to ensure the family fully understands the information.
If genetic testing is needed, the counsellor discusses available options, explains the consent process, and helps the family prepare for testing. Genetic counsellors interpret the genetic test results and explain the health implications for individuals.
They also recommend resources, including support groups, to help families connect with others facing similar challenges. Access to these groups provides emotional support and practical insights, reducing feelings of isolation and helping families adapt to their diagnosis.
Emotional and Psychosocial Support
Genetic counselling provides crucial emotional support for individuals and families navigating complex genetic information. The process addresses the profound psychological challenges that can arise when confronting genetic information and diagnoses. Counsellors help individuals process the emotional weight of understanding genetic risks, creating a supportive environment to explore sensitive topics such as inherited condition probabilities and the potential consequences of genetic testing. By offering compassionate assistance, these professionals help people manage the emotional uncertainty and stress that often accompany genetic health discussions.
Ethics and Confidentiality in Genetic Counselling
Genetic counselling follows strict ethical principles, meaning it is based on fairness, respect, and doing what is right for individuals and families. It also includes strict confidentiality practices to protect personal information. Counsellors follow privacy laws to ensure that genetic information remains secure and confidential. A non-directive counselling approach is employed, allowing patients to make informed decisions without undue influence. Informed consent is a cornerstone of the process, ensuring individuals fully understand the implications of genetic testing or any procedures involved. Additionally, counsellors maintain secure documentation systems to safeguard sensitive information and uphold the highest standards of ethical practice.
Finding Your Genetic Counsellor
You can begin by asking your doctor for a recommendation, as they may have connections to trusted professionals. Additionally, online directories offer a convenient way to search for genetic counsellors in your area or through virtual services.
Patient advocacy groups can also provide valuable referrals and guidance, connecting you with experienced counsellors familiar with specific conditions or concerns.
Finding a genetic counsellor has become more accessible with advancements in telehealth and technology, eliminating the need to visit a distant medical centre where genetic counselling services are available.
