Whole Genome Screening

Whole genome sequencing can provide a wealth of information, but genetic data alone rarely tells the full story. The most meaningful insights come from interpreting genetic findings alongside an individual’s medical history, family history, lifestyle, and clinical assessment.

At The London Genetics Centre, whole genome screening is integrated into a comprehensive medical evaluation. This approach helps ensure that genetic findings are placed in the appropriate clinical context, allowing recommendations to be tailored to the individual rather than based on genetic results alone.

A Multidisciplinary Team of Genetics Specialists

Our team brings together expertise across cancer genetics, cardiovascular genetics, general genetics, and paediatric genetics. This breadth of experience enables us to assess a wide range of inherited conditions and provide comprehensive guidance for patients and their families.

Genetics is a rapidly evolving field, requiring careful interpretation and specialist expertise. Our consultants work collaboratively to review findings, assess clinical relevance, and help patients understand how genomic information may inform their healthcare decisions.

Whole Genome Screening as Part of Preventive Healthcare

Traditional medical practice has always relied on understanding the individual as a whole—combining personal medical history, family history, examination, and appropriate investigations. Whole genome screening adds a powerful new dimension to this process by providing insights into inherited health risks that may not otherwise be apparent.

When combined with expert clinical assessment, genomic information can support earlier detection, personalised screening strategies, and more informed long-term healthcare planning.

Pioneering Preventive Genomics

The London Genetics Centre has been at the forefront of integrating whole genome sequencing into clinical practice. Our approach combines advanced genomic analysis with specialist medical expertise, helping individuals gain a deeper understanding of their health and supporting a more personalised approach to prevention and wellbeing.

One of the most important principles of preventive genomic screening is focusing on findings that have the potential to inform healthcare decisions.

Whole genome sequencing can identify thousands of genetic variations. However, not every genetic finding is clinically meaningful or requires medical action. At The London Genetics Centre, our analysis prioritises genes associated with conditions where early detection, screening, monitoring, or intervention may help reduce risk or improve health outcomes.

These may include inherited predispositions to certain cancers, cardiovascular conditions, and other medically actionable disorders. By concentrating on clinically relevant findings, we aim to provide information that can support practical and informed healthcare planning.

As genomic medicine continues to advance, our understanding of actionable genetic findings will evolve, allowing genomic screening to play an increasingly important role in personalised healthcare and prevention.

Pharmacogenomics: How Your Genes Can Influence Medication Response

People can respond differently to the same medication, and part of that variation is determined by genetics.

Pharmacogenomics is the study of how genetic differences influence the way the body processes and responds to medicines. Genetic variation can affect how medications are absorbed, activated, metabolised, and cleared from the body, influencing both effectiveness and the likelihood of side effects.

As part of whole genome screening, pharmacogenomic analysis may provide insights that help healthcare professionals make more personalised prescribing decisions. In some cases, this information may support medication selection, dosing considerations, or the avoidance of treatments that may be less suitable for a particular individual.

By combining pharmacogenomic insights with clinical assessment, healthcare professionals can take a more personalised approach to treatment, helping optimise both safety and effectiveness.

Whole Genome Screening Pathway

The Practicalities – How is it done?

The journey begins with a full Medical at 90 Sloane Street or an accepted GP partner centre. This includes a full history of current and past illnesses, together with family history and any medication taken. You will undergo a detailed examination, a blood screen, ECG, echocardiogram as well as an abdominal and pelvic ultrasound. All these tests are non-invasive and have no radiation.

We will discuss Colonoscopy screening benefits and sometimes CT coronary angiogram screening options individually but they are not part of our Whole Genome Screening.

When you apply for Whole Genome Screening at The London Genetics Centre you will be emailed an information pack.

This includes a more detailed explanation of the pathway, our Welcome Letter, a family history questionnaire to fill in and consent forms to read and for your own record. You can then email the family history questionnaire back to us and book your appointment/medical. You will have a 30-minute pre-test counselling session immediately after your medical where any remaining questions and queries about the test can be addressed and the consent forms signed. Your sample will be sent off after this. This is a 30-minute appointment immediately after your full medical, and following which your whole genome sequencing test can be sent off.

Where and Who will be conducting various aspects of the different tests?

All tests will be done at The London Genetics Centre. Other partnership practices can do the Medical part for their own patients.

You will have your Medical with a GP. The heart tests, ECG and Echocardiogram will be done by our cardiac technician. The ultrasound is done by a specialist radiologist. You receive your genome result with a Consultant Geneticist at The London Genetics Centre, this can be face-to-face or using Zoom if you prefer.

We are doing Whole Genome Sequencing as a part of best medical care with a full medical assessment.

We have developed the ‘Next Generation Screening’.

One of the greatest benefits of whole genome screening is the ability to identify inherited health risks before symptoms develop. In some cases, this information may support earlier screening, enhanced monitoring, preventive interventions, or personalised treatment strategies.

Cancer Predisposition

Certain inherited genetic variants can increase an individual’s risk of developing cancer. Identifying these risks can allow screening programmes to be tailored to the individual, potentially leading to earlier detection and improved outcomes.

Whole genome screening may identify inherited predispositions to cancers including:

• Breast cancer

• Ovarian cancer

• Colorectal cancer

• Prostate cancer

• Other hereditary cancer syndromes

For some individuals, genetic findings may influence decisions regarding screening frequency, surveillance strategies, risk-reducing interventions, or family testing.

Inherited Cardiovascular Conditions

Inherited cardiovascular disorders are an important cause of serious illness and, in some cases, sudden cardiac events. Genetic screening can help identify individuals who may benefit from additional assessment, monitoring, or preventive treatment.

Examples include:

Cardiomyopathies

Inherited conditions affecting the heart muscle can sometimes be identified before symptoms develop. When combined with cardiac imaging such as echocardiography, genetic findings may support earlier diagnosis and ongoing monitoring.

Inherited Heart Rhythm Disorders

Certain genetic variants can increase susceptibility to abnormal heart rhythms. Early identification may help guide lifestyle recommendations, medication choices, and specialist cardiac follow-up.

Aortic Conditions

Some inherited conditions can affect the body’s major arteries. Recognising these risks may enable appropriate imaging surveillance and early intervention when required.

Familial Hypercholesterolaemia

This inherited condition can result in significantly elevated cholesterol levels from an early age. Early diagnosis allows treatment strategies that may substantially reduce long-term cardiovascular risk.

Other Medically Actionable Findings

Whole genome screening may also identify inherited conditions beyond cancer and cardiovascular disease where preventive measures, monitoring, or treatment can reduce health risks.

Examples include conditions affecting blood clotting, iron metabolism, and other inherited disorders where early identification may inform healthcare decisions and improve outcomes.

Turning Genetic Information into Action

The value of genomic screening lies not simply in identifying genetic variants, but in understanding what those findings mean for the individual.

At The London Genetics Centre, genomic findings are reviewed alongside personal and family history by experienced genetics specialists. This integrated approach helps translate complex genetic information into practical recommendations for prevention, screening, and long-term health planning.

Genetic testing has evolved significantly over the past decade. While many genetic tests focus on specific genes or groups of genes associated with a particular condition, Whole Genome Sequencing (WGS) provides the most comprehensive analysis currently available.

Rather than examining selected areas of DNA, WGS analyses an individual’s entire genetic code, enabling a broader assessment of inherited health risks and clinically actionable findings.

Understanding the Different Types of Genetic Testing

Single Gene Testing

Single gene testing focuses on one specific gene and is typically used when there is a strong suspicion of a particular inherited condition or when testing family members for a known genetic variant.

Gene Panel Testing

Gene panels analyse groups of genes associated with a particular condition, such as inherited cancer syndromes or cardiovascular disorders. These tests are highly effective when there is a specific clinical question being investigated.

Whole Genome Sequencing

Whole Genome Sequencing examines the complete genome, providing a broader assessment of inherited risk factors across multiple areas of health. This approach allows analysis of both well-established disease-associated genes and additional genomic information that may support future healthcare planning.

Beyond Traditional Genetic Testing

Whole Genome Sequencing can provide insights that extend beyond single-gene disorders.

In addition to identifying inherited variants associated with certain cancers, cardiovascular conditions, and other actionable disorders, genomic analysis may also contribute to a deeper understanding of an individual’s overall risk profile through emerging approaches such as polygenic risk assessment.

As genomic medicine continues to advance, the value of whole genome data is expected to grow, allowing new insights to be derived from information that has already been generated.

Pharmacogenomics: Personalising Medication Decisions

Genetics can influence the way individuals respond to medicines.

Pharmacogenomic analysis examines genetic factors that may affect how medications are processed within the body. In some cases, this information can help healthcare professionals make more personalised prescribing decisions, supporting medication selection, dosing considerations, and the management of potential side effects.

By combining genomic insights with clinical expertise, healthcare can become increasingly tailored to the individual.

From Data to Action

The true value of whole genome sequencing lies not simply in generating genetic information, but in understanding what that information means for the individual.

At The London Genetics Centre, genomic findings are reviewed by experienced genetics specialists and considered alongside personal medical history, family history, and clinical assessment. This integrated approach helps translate complex genetic information into meaningful recommendations for prevention, screening, and long-term health planning.

Who is eligible for Whole Genome Screening?

Whole Genome Screening is currently available for adults aged 25 years and over. There is no upper age limit.

For younger individuals with a significant personal or family history of an inherited condition, a consultation with one of our genetics specialists may be appropriate to discuss tailored testing options.

Is Whole Genome Screening suitable for everyone?

Genetic testing may not be appropriate in every circumstance. As part of the consultation process, we assess whether genomic screening is suitable for each individual and discuss the potential benefits, limitations, and implications of testing.

Our priority is to ensure that patients feel informed, supported, and confident in their decision-making.

What support is available if I receive an important genetic finding?

Receiving genetic information can sometimes feel overwhelming, particularly when a previously unknown health risk is identified.

Our multidisciplinary team includes experienced consultant geneticists and genetic counsellors who provide clear explanations, guidance, and ongoing support. Where appropriate, we can also facilitate access to additional psychological support and specialist referrals.

Why is genetic counselling important?

Genetic testing is most valuable when accompanied by expert interpretation and support.

Our genetics specialists help patients understand the significance of their results, discuss implications for personal health and family members, and guide decisions regarding screening, prevention, and further care.

This integrated approach is a key part of The London Genetics Centre’s commitment to delivering personalised genomic healthcare.

Will my genetic test results affect my insurance?

The implications of genetic testing for insurance can vary depending on individual circumstances and jurisdiction.

In the UK, a voluntary agreement currently exists between the Government and the insurance industry regarding the use of predictive genetic test results in most insurance applications. However, policies and regulations may change over time.

Patients are encouraged to seek independent financial or legal advice if they have concerns regarding insurance, employment, or other personal considerations before undergoing genetic testing.

What sample is required?

Genomic testing is typically performed using a blood sample. However, for individuals who are unable to provide a blood sample, saliva-based testing may be available as an alternative.

Our Whole Genome Screening Programme combines advanced genomic analysis with comprehensive clinical assessment and specialist interpretation.

The programme includes:
