01

Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Recurrent or severe infections
  • ✓Failure to thrive
  • ✓Developmental delays
  • ✓Family history of immunodeficiency
  • ✓Suspected SCID
  • ✓Microcephaly or growth retardation
02

In plain language

What this test helps you understand

This test helps identify genetic mutations in the NHEJ1 gene, which can cause severe combined immunodeficiency (SCID), microcephaly, growth retardation, and sensitivity to ionizing radiation. Identifying these mutations can guide diagnosis, prognosis, and management strategies.
This genetic test identifies specific mutations in the NHEJ1 gene linked to severe combined immunodeficiency (SCID) and related conditions. It uses advanced Next Generation Sequencing (NGS) technology to analyze DNA samples. Early diagnosis is crucial for managing these complex conditions and implementing appropriate medical interventions. This test is recommended for individuals presenting with symptoms suggestive of immunodeficiency or related developmental issues.

SampleBlood sample (EDTA tube). Confirm specific requirements with the laboratory before booking.
MethodologyNext Generation Sequencing (NGS) of the NHEJ1 gene.
PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test analyzes the NHEJ1 gene specifically. It may not detect mutations in other genes that can cause similar conditions. Results are indicative and require clinical correlation. Confirm with the laboratory for a full list of limitations.

Questions people ask

Frequently asked questions

SCID stands for Severe Combined Immunodeficiency. It is a group of rare genetic disorders characterized by a severely weakened immune system, making individuals highly susceptible to infections.
The NHEJ1 gene provides instructions for making a protein involved in repairing DNA breaks. Mutations in this gene can disrupt DNA repair processes, leading to the symptoms associated with the condition.
Individuals with symptoms like frequent infections, poor growth, or developmental delays, especially infants and children, may be candidates for this test. A doctor's recommendation is advised.
A genetic counselor or physician will interpret the results in the context of your medical history and symptoms. Discuss the findings and their implications with your healthcare provider.
Yes, genetic counseling before and after testing is highly recommended to understand the test's implications, potential results, and available options.
