Understanding Your Results

Results indicate the presence or absence of mutations in the LRMDA gene associated with OCA7 albinism. Positive results confirm diagnosis, while negative results may require further testing if symptoms persist.
Pathogenic variant detected: Confirms OCA7 diagnosis
Variant of uncertain significance: Requires further evaluation
No variant detected: OCA7 unlikely, consider other types of albinism
⚠️ When to Consult a Doctor:

If you experience symptoms of albinism such as pale skin, vision problems, or have a family history of the condition, consult a healthcare provider for genetic testing and counseling.

Frequently Asked Questions

What is Oculocutaneous Albinism Type 7 (OCA7)?
OCA7 is a rare genetic disorder caused by mutations in the LRMDA gene, leading to reduced melanin production and symptoms like pale skin, light hair, and vision problems.
How is the LRMDA Gene NGS Test performed?
The test uses Next-Generation Sequencing to analyze the LRMDA gene from a blood or DNA sample, identifying mutations associated with OCA7.
What are the common symptoms of OCA7?
Symptoms include pale skin that burns easily, light-colored hair and eyes, nystagmus, reduced visual acuity, sensitivity to light, and strabismus.
Who should consider getting this genetic test?
Individuals with symptoms of albinism, a family history of OCA7, or those planning for family genetic counseling should consider this test.
What is the cost of the LRMDA Gene Albinism Test?
The test costs INR 20,000, which includes sample collection, analysis, and report delivery.
How long does it take to receive the test results?
Results are typically available within 3 to 4 weeks after sample collection.
Is home sample collection available for this test?
Yes, DNA Labs India offers free home sample collection across India for online bookings.
What do the test results indicate?
Results show whether pathogenic mutations in the LRMDA gene are detected, confirming OCA7 diagnosis, or if no variants are found.
Can this test be used for prenatal diagnosis?
This test is primarily for postnatal diagnosis. For prenatal testing, consult a genetic counselor for appropriate options.
Is genetic counseling recommended before or after the test?
Yes, genetic counseling is advised to understand the implications, interpret results, and discuss family planning.
What are the risks associated with this genetic test?
Risks are minimal, such as discomfort from blood draw, but genetic results may have psychological impacts, hence counseling is important.
How accurate is the NGS Genetic Test for OCA7?
The test is highly accurate due to advanced NGS technology, but accuracy depends on sample quality and variant detection capabilities.
