Receiving a laboratory report related to 1p36 Deletion Syndrome can feel overwhelming, particularly if the terminology is unfamiliar. This educational guide is designed to help individuals and families in London and across the UK understand what their 1p36 Deletion Syndrome laboratory report results may indicate, what key markers mean, and how to approach next steps in an informed, calm manner.
At Private Blood Tests London, our nurse-led clinic provides professional testing and detailed reporting to support your health awareness journey — without GP referral requirements and without unnecessary delays.
What Is 1p36 Deletion Syndrome? A Clear Definition
1p36 Deletion Syndrome is a chromosomal condition caused by the deletion of genetic material at the tip of chromosome 1 (the short arm, referred to as "1p36"). It is one of the most commonly identified terminal deletion syndromes in clinical genetics.
In laboratory terms, this deletion is identified through cytogenetic or molecular testing and is reported in your results document with specific markers indicating the size, location, and extent of the chromosomal deletion. Understanding these details is the first step toward navigating your report with greater confidence.
> Snippet Definition: 1p36 Deletion Syndrome is a chromosomal disorder resulting from a missing segment at the end of chromosome 1's short arm. Laboratory reports confirm this through genomic analysis, detailing the deletion size and region affected, which may influence associated clinical features and further care pathways.
Key Laboratory Tests Used to Identify 1p36 Deletions
Laboratory identification of 1p36 Deletion Syndrome typically involves one or more of the following genomic testing methods:
| Test Type | What It Detects | Common Reporting Format |
|---|---|---|
| Chromosomal Microarray (CMA) | Copy number variants, deletion size | Genomic coordinates (e.g., chr1:1–5,000,000) |
| Fluorescence In Situ Hybridisation (FISH) | Targeted deletion at 1p36 locus | Positive/Negative signal result |
| Whole Genome Sequencing (WGS) | Deletion boundaries, gene content | Variant classification report |
| Karyotyping | Large chromosomal deletions | Numbered chromosome analysis |
| SNP Array | Deletion and uniparental disomy | Allele frequency graphs |
Each of these test types produces a slightly different report format, and understanding which test was used is essential before interpreting any figures or classifications within your results.

How to Read Your Laboratory Report: Section by Section
Patient and Sample Information
Your report will begin with demographic and sample details, including the date of collection, sample type (blood, saliva, or amniotic fluid), and the requesting clinician's information. Always verify these details are correct before reviewing findings.
Genomic Findings Section
This is the core of your report. You may see language such as:
Deletion Size and Clinical Relevance
Deletion sizes are typically reported in megabases (Mb) or kilobases (Kb):
Practical Insight: The size of the deletion does not always directly predict clinical presentation — individual variation exists, and this information is best interpreted alongside appropriate healthcare guidance.
Reference Ranges and Normal Values
In chromosomal reporting, the concept of a "normal range" differs from standard blood tests. A normal result would typically report 46,XX or 46,XY (the standard human chromosome count) with no deletions noted. Any deviation from this is flagged and classified by clinical significance.
Who May Receive This Type of Laboratory Report?
A 1p36 Deletion Syndrome genomic laboratory report may be relevant for:
At our clinic, we support individuals seeking clarity around laboratory reports through professional testing services. We provide detailed, accurate reporting to help you understand your results in plain language.
Practical Insight: Having access to a clear, well-formatted laboratory report is the foundation of any informed conversation with an appropriate healthcare professional.
Understanding the Frequency of Testing and Follow-Up Reporting
Chromosomal testing for 1p36 Deletion Syndrome is generally a once-in-a-lifetime diagnostic test — the chromosomal result itself does not change over time. However, follow-up laboratory monitoring may be recommended for associated health parameters, which can include:
For those wishing to monitor general health markers alongside a known chromosomal condition, our comprehensive health screening packages may offer a practical, accessible option in London.
What Do the Classifications in Your Report Actually Mean?
Understanding the classification tier used in your genomic report is crucial:
Practical Insight: Seeing "Pathogenic" in your report can feel alarming. It is a classification term used for scientific accuracy — it does not define a person's potential or quality of life, and it is best discussed with a qualified genetic counsellor or appropriate healthcare professional.

Frequently Asked Questions (FAQ)
1. What does a 1p36 Deletion Syndrome laboratory report result mean?
A 1p36 Deletion Syndrome laboratory report result indicates whether genetic material is missing from the short arm of chromosome 1. The report will classify the finding (e.g., pathogenic, VUS, or negative) and detail the size and location of any identified deletion. It is an informational document that should be reviewed alongside an appropriate healthcare professional or genetic counsellor for full contextual understanding.
2. Is a 1p36 deletion always detected by standard blood tests?
No. Standard blood tests such as full blood counts or biochemistry panels do not detect chromosomal deletions. Specific genomic tests — such as chromosomal microarray, FISH, or whole genome sequencing — are required to identify a 1p36 deletion. These are specialist molecular diagnostic tests that produce a separate, dedicated laboratory report.
3. What does "pathogenic" mean in a chromosomal report?
"Pathogenic" is a scientific classification indicating that the identified genetic change is associated with a known clinical condition. In the context of 1p36 Deletion Syndrome, it means the deletion at chromosome 1p36 has been confirmed as clinically significant. This classification does not imply severity or predict outcomes — it is a reporting standard used in genomic medicine.
4. What is a Variant of Uncertain Significance (VUS) in a 1p36 report?
A VUS means that the identified genetic variant cannot currently be classified as definitively pathogenic or benign. It does not mean the result is harmful. As genomic research advances, VUS classifications can be updated. It is important to discuss a VUS finding with a genetic counsellor who can provide contextual interpretation.
5. Can adults receive a 1p36 Deletion Syndrome laboratory report?
Yes. While 1p36 Deletion Syndrome is often identified in childhood, adults may receive a related laboratory report if seeking clarification of an earlier diagnosis, undergoing reproductive carrier testing, or pursuing private genomic testing for personal health awareness. Our London clinic supports adults seeking professional testing and detailed reporting services.
6. How long does it take to receive a 1p36 chromosomal laboratory report?
Turnaround times vary depending on the testing method used. Chromosomal microarray results typically take 2–4 weeks. FISH testing may return faster, while whole genome sequencing can take longer. At Private Blood Tests London, we will advise on expected timeframes at the point of testing. Results are provided in a clear, professionally formatted report.
7. What should I do after receiving my 1p36 Deletion Syndrome laboratory results?
After receiving your 1p36 Deletion Syndrome laboratory report results, we recommend reviewing the findings with an appropriate healthcare professional — such as a genetic counsellor, paediatrician, or clinical geneticist — who can provide contextual interpretation. Our clinic provides professional reporting; interpretation and management planning should be guided by a suitably qualified healthcare provider.
8. Does the NHS test for 1p36 Deletion Syndrome?
Yes, the NHS offers genomic testing through clinical genetics departments, typically via referral from a paediatrician or other specialist.
