Understanding Your Results

Results indicate the presence or absence of mutations in the BLK gene associated with MODY Type 11, aiding in diagnosis and management.
📊

Negative for pathogenic variants

No mutations detected in BLK gene; MODY Type 11 unlikely based on this test

📊

Positive for pathogenic variant

Mutation detected in BLK gene; consistent with MODY Type 11 diagnosis, confirm with clinical evaluation

📊

Variant of uncertain significance (VUS)

Genetic variant found but significance unknown; further testing or clinical correlation needed

⚠️ When to Consult a Doctor:

Consult a doctor if you experience symptoms of diabetes, have a family history of MODY, or receive a positive test result for appropriate management and genetic counseling.

Limitations

Frequently Asked Questions

What is BLK Gene MODY Type 11?
MODY Type 11 is a rare form of monogenic diabetes caused by mutations in the BLK gene, leading to impaired insulin secretion and diabetes symptoms in young adults.
Who should consider the BLK Gene MODY Type 11 NGS Genetic Test?
Young adults with diabetes symptoms, especially those with a family history of MODY or diabetes not typical of Type 1 or Type 2, should consider this test.
What are the symptoms of MODY Type 11?
Symptoms include increased thirst, frequent urination, blurred vision, fatigue, and weight loss, similar to other diabetes types but often onset before age 25.
How is the test performed?
The test uses next-generation sequencing (NGS) to analyze DNA from a blood sample or extracted DNA, detecting mutations in the BLK gene.
What is the cost of the BLK Gene MODY Type 11 NGS Genetic Test?
The cost is INR 20,000 at DNA Labs India, which includes the test and a genetic counseling session.
Is home sample collection available for this test?
Yes, DNA Labs India offers free home sample collection across India for online bookings.
How long does it take to receive the test results?
Results are typically available within 3 to 4 weeks after sample collection.
What does a positive test result mean?
A positive result indicates a mutation in the BLK gene, supporting a diagnosis of MODY Type 11; clinical correlation is recommended.
Can MODY Type 11 be managed without insulin therapy?
Often, yes. Management may include diet, exercise, and oral medications, but consultation with a doctor is essential for personalized care.
Is genetic counseling included in the test package?
Yes, a genetic counseling session is included to help interpret results and discuss implications for family members.
How accurate is the NGS genetic test for MODY Type 11?
NGS technology offers high accuracy for detecting mutations, but no genetic test is 100% infallible; clinical evaluation is important for confirmation.
What should I do after receiving the test results?
Discuss results with a genetic counselor or healthcare provider to understand diagnosis, management options, and family risk assessment.
