Understanding Your Results

Results from the LAS1L Gene NGS Genetic Test indicate the presence or absence of mutations in the LAS1L gene associated with Wilson-Turner syndrome. Interpretation should be done by a qualified geneticist or healthcare provider.
Positive result: Pathogenic mutation detected in the LAS1L gene, consistent with a diagnosis of Wilson-Turner syndrome
Negative result: No pathogenic variants detected, but clinical symptoms may warrant further testing or evaluation
Variant of uncertain significance (VUS): Genetic change identified but not clearly linked to disease; requires follow-up
⚠️ When to Consult a Doctor:

Consult a healthcare provider if symptoms of Wilson-Turner syndrome are present, for genetic counseling, or to discuss test results and management options.

Frequently Asked Questions

What is Wilson-Turner syndrome?
Wilson-Turner syndrome is a rare genetic disorder that affects only females, caused by mutations in the LAS1L gene on the X chromosome, leading to developmental delays, intellectual disabilities, and distinctive facial features.
How is the LAS1L Gene NGS Genetic Test performed?
The test uses Next-Generation Sequencing (NGS) technology to analyze the entire coding region of the LAS1L gene from a blood or DNA sample to detect mutations.
What is the cost of the LAS1L Gene NGS Genetic Test?
The test costs INR 20,000 at DNA Labs India, with free home sample collection available across India.
Who should consider this test?
This test is recommended for females with symptoms such as developmental delays, intellectual disabilities, distinctive facial features, or a family history of Wilson-Turner syndrome.
What sample is required for the test?
The test requires a blood sample, extracted DNA, or one drop of blood on an FTA card.
How long does it take to get results?
Results are typically available within 3-4 weeks after sample collection.
Is fasting required before the test?
No, fasting is not required for this genetic test.
What do the test results mean?
Results indicate whether pathogenic mutations in the LAS1L gene are detected. A positive result suggests Wilson-Turner syndrome, while a negative result may require further clinical evaluation.
Is the test covered by insurance?
Coverage depends on the insurance provider and policy. It is advisable to check with your insurer for specific details.
Can the test be done at home?
Yes, DNA Labs India offers free home sample collection for online bookings across many cities in India.
What are the limitations of this test?
The test only detects mutations in the LAS1L gene and may not identify all genetic variations. Results should be interpreted in conjunction with clinical findings.
How can I prepare for genetic counseling?
Prepare by gathering family medical history and discussing symptoms with a healthcare provider. A genetic counselor will help draw a pedigree chart and explain test implications.
