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.

  • ✓Family history of sudden cardiac death
  • ✓Unexplained fainting spells (syncope)
  • ✓Diagnosis of congenital long QT syndrome
  • ✓Personal history of arrhythmias
  • ✓Family history of Jervell and Lange-Nielsen Syndrome
  • ✓Pre-symptomatic screening in high-risk families

In plain language

What this test helps you understand

This test helps identify individuals with mutations in the KCNQ1 gene, which are associated with Jervell and Lange-Nielsen Syndrome. This information can aid in diagnosis, risk assessment, and management strategies for individuals and families affected by this condition.
This test analyzes the KCNQ1 gene to detect mutations linked to Jervell and Lange-Nielsen Syndrome (JLNS). JLNS is a genetic disorder characterized by congenital long QT syndrome, which can lead to dangerous heart rhythm disturbances (arrhythmias) and fainting. Identifying these mutations is crucial for understanding risk and guiding management.

This test specifically looks for changes in the KCNQ1 gene, which provides instructions for making a protein important for the electrical activity of heart cells. Mutations in this gene can disrupt normal heart function.

Understanding your genetic predisposition can help in making informed decisions about your health and potentially guide family members.

PreparationA detailed clinical history is required. Genetic counseling, including pedigree chart creation, is necessary before testing.
SampleBlood sample (EDTA tube), extracted DNA, or dried blood spot on FTA card.
MethodologyNext Generation Sequencing (NGS) analysis of the KCNQ1 gene.
PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test analyzes only the KCNQ1 gene. Other genes can also cause similar conditions. The test may not detect all possible mutations within the KCNQ1 gene. Results should be interpreted in the context of clinical findings and family history.

What common result terms mean

PositiveA finding was identified. Your clinician or counselor will explain what it means for your care.
NegativeThe specific finding tested for was not identified. It does not rule out every possible cause.
VUSA variant was found, but current evidence is not enough to classify it. Your counselor can explain follow-up.

Questions people ask

Frequently asked questions

Jervell and Lange-Nielsen Syndrome (JLNS) is a rare genetic disorder characterized by congenital long QT syndrome, which affects the heart's electrical activity, and sensorineural deafness.
Mutations in the KCNQ1 gene are a known cause of JLNS. Identifying these mutations helps confirm the diagnosis, understand the risk of life-threatening heart rhythms, and guide management.
Individuals with a family history of JLNS, sudden cardiac death, unexplained fainting, or diagnosed long QT syndrome should discuss this test with their doctor.
The test requires a sample of blood or DNA. A clinical history and genetic counseling session are also needed before testing.
Results indicate the presence or absence of specific mutations in the KCNQ1 gene. A genetic counselor or physician will help interpret the results in the context of your medical history.
While the test identifies genetic mutations associated with increased risk, it cannot definitively predict future health outcomes. Management strategies can help mitigate risks.
