What Is a 1p36 Deletion? A Clear Definition
1p36 deletion syndrome is a chromosomal condition caused by the loss of genetic material from the very tip of chromosome 1 (the short arm, at position 36). It is one of the most commonly identified subtelomeric deletion disorders in humans, estimated to occur in approximately 1 in 5,000–10,000 live births.
The syndrome can affect multiple body systems, including neurological development, cardiac function, thyroid activity, immune response, and metabolic regulation. Because of this wide-ranging systemic impact, early identification and ongoing health monitoring are widely regarded within UK clinical guidance as central to supporting improved quality of life.
> Practical Insight: A 1p36 deletion diagnosis is not a single clinical event — it marks the beginning of a long-term health monitoring journey that benefits enormously from structured, proactive support.

Why Early Intervention Following a 1p36 Deletion Diagnosis Matters
Following a confirmed 1p36 deletion diagnosis, early intervention is widely associated with improved outcomes across multiple health domains. The rationale is well-supported in UK paediatric and adult health literature: the earlier that systemic imbalances are identified, the more effectively they can be addressed by appropriate healthcare professionals.
Key areas where early monitoring may be particularly valuable include:
Early, structured blood testing does not replace specialist clinical care — but it can generate objective data that supports more informed conversations with your healthcare team.
> Practical Insight: Monitoring biomarkers proactively allows families and healthcare professionals to detect subtle shifts before they become more complex health concerns.
Who Should Consider Ongoing Blood Testing After a 1p36 Deletion Diagnosis?
| Group | Monitoring Consideration |
|---|---|
| Infants and children with confirmed 1p36 deletion | Baseline nutritional and thyroid panels may be recommended by clinical teams |
| Adolescents with 1p36 deletion | Metabolic and hormonal markers may become relevant as growth progresses |
| Adults with 1p36 deletion | Ongoing thyroid, metabolic, and immune monitoring can support long-term wellbeing |
| Parents and caregivers seeking data | Private blood testing may support more informed discussions with NHS teams |
| Families awaiting NHS referrals | Private testing can provide timely baseline data while waiting for specialist appointments |
> Practical Insight: For families navigating NHS waiting lists or seeking a more immediate picture of current health status, private blood testing in London can offer a timely, accessible option.
How Often Should Health Monitoring Take Place?
Frequency of monitoring will always depend on individual clinical circumstances, and guidance should come from the healthcare professionals involved in each person's care. However, as a general educational framework:
At Private Blood Tests London, our nurse-led service provides straightforward, professional blood testing without the need for a GP referral. We provide testing and full written reporting — allowing you to take results directly to your chosen healthcare provider.
Key Biomarkers to Consider Following a 1p36 Deletion Diagnosis
Understanding which blood markers are most relevant can help families have more informed discussions with clinical teams. The following biomarkers are frequently discussed in the context of 1p36 deletion syndrome:
Thyroid Function
Thyroid Stimulating Hormone (TSH), Free T3, and Free T4 levels may indicate how the thyroid gland is functioning. Hypothyroidism — where the thyroid is underactive — is reported in a meaningful proportion of individuals with 1p36 deletion and may manifest as fatigue, weight changes, or developmental concerns.
Nutritional Panel
Vitamin D deficiency is common in the UK population broadly, and may be more prevalent in individuals with feeding difficulties. Iron, B12, and folate levels can also provide useful information, particularly where dietary intake may be limited.
Metabolic Markers
Fasting glucose, HbA1c (a longer-term blood sugar marker), and a lipid profile (including total cholesterol, HDL, and LDL) can sometimes highlight patterns that warrant attention.
Immune and Inflammatory Markers
A full blood count (FBC) can provide a broad snapshot of immune cell distribution and flag potential concerns around infection susceptibility or inflammation.
Liver and Kidney Function
Liver enzymes and kidney function tests may be relevant in individuals on long-term medications or where systemic health is being comprehensively assessed.
Our full blood count testing and thyroid function testing services are available without a GP referral at our London clinic.
> Practical Insight: No single blood test defines a person's health — but a thoughtfully selected panel can provide a meaningful, objective snapshot that supports clinical decision-making.

Frequently Asked Questions (FAQ)
1. What is a 1p36 deletion diagnosis?
A 1p36 deletion diagnosis refers to the confirmed identification of a chromosomal condition caused by missing genetic material at the tip of chromosome 1. It can affect multiple body systems, including neurological development, thyroid function, cardiac health, and immune response. The condition varies widely in severity between individuals and is typically identified through chromosomal microarray testing ordered by a clinical geneticist or paediatrician.
2. Why is early intervention important following a 1p36 deletion diagnosis?
Early intervention following a 1p36 deletion diagnosis is widely regarded as important because many of the associated health concerns — such as thyroid dysfunction, nutritional deficiencies, and metabolic changes — may be subtle in their early stages. Regular blood monitoring can help healthcare professionals identify emerging patterns and respond appropriately, supporting better long-term management of the condition.
3. Can private blood tests support a 1p36 deletion diagnosis journey?
Private blood tests can provide timely, objective data that may support the broader management of health following a 1p36 deletion diagnosis. While private clinics like ours do not offer diagnosis, treatment, or specialist care, we can provide accurate blood test results that families can share with their NHS or private clinical teams to inform further care decisions.
4. Which blood tests are most relevant for individuals with 1p36 deletion syndrome?
Commonly discussed blood markers in the context of 1p36 deletion syndrome include thyroid function (TSH, T3, T4), a full blood count, nutritional panels (vitamin D, iron, B12, folate), metabolic markers (glucose, HbA1c, cholesterol), and liver and kidney function tests. The most appropriate panel for any individual should be guided by their clinical team based on their specific health history.
5. How often should blood tests be carried out after a 1p36 deletion diagnosis?
Frequency of testing should always be guided by the healthcare professionals involved in an individual's care. In general clinical discussions, annual monitoring is often mentioned for individuals with chromosomal conditions affecting multiple systems, with more frequent testing recommended when specific markers have previously been flagged or when health changes occur.
6. Do I need a GP referral to access private blood testing in London?
No — at Private Blood Tests London, you do not need a GP referral to access our blood testing services. Our nurse-led clinic provides professional blood collection and written reporting. Results can then be shared with your GP, paediatrician, or any other healthcare professional involved in your care.
7. Is private blood testing a replacement for NHS specialist care?
No. Private blood testing is a complementary tool — not a replacement for specialist NHS or private medical care. Our clinic provides testing and reporting only. We do not offer diagnosis, treatment, or prescriptions. Families are always encouraged to work closely with their clinical teams when interpreting results and making healthcare decisions.
8. Can adults with 1p36 deletion syndrome also benefit from regular blood monitoring?
Yes. While 1p36 deletion is often identified in childhood, adults with the condition may also benefit from regular health monitoring. Thyroid function, metabolic health, and nutritional status can all shift over time, and ongoing blood testing may help support informed conversations with healthcare providers throughout adulthood.
