Frequently Asked Questions

What is ILDR1 gene deafness?
ILDR1 gene deafness is a genetic condition caused by mutations in the ILDR1 gene, leading to autosomal recessive type 42 deafness, characterized by sensorineural hearing loss.
How is ILDR1 gene deafness inherited?
It is inherited in an autosomal recessive pattern, meaning both parents must carry a mutated copy of the ILDR1 gene for a child to be affected.
What are the symptoms of ILDR1 gene deafness?
Symptoms include difficulty hearing, partial or complete deafness, tinnitus, vertigo, and balance problems, which may appear from birth or later in life.
How is ILDR1 gene deafness diagnosed?
Diagnosis involves clinical examination, hearing tests, and genetic testing using NGS to detect mutations in the ILDR1 gene.
What is NGS genetic testing?
Next-generation sequencing (NGS) is a advanced technology that analyzes DNA to identify genetic mutations, such as those in the ILDR1 gene.
What does the ILDR1 gene test involve?
The test involves collecting a blood or DNA sample, which is analyzed using NGS to screen for mutations in the ILDR1 gene.
How long does it take to get results?
Results are typically available within 3 to 4 weeks after sample collection.
What is the cost of the ILDR1 gene test in India?
The cost at DNA Labs India is INR 20,000, which includes sample collection, analysis, and report generation.
Is home sample collection available?
Yes, DNA Labs India offers free home sample collection for this test across many cities in India.
Who should consider this test?
Individuals with symptoms of hearing loss, balance issues, or a family history of genetic deafness should consider this test.
What if the test result is positive?
A positive result confirms ILDR1 gene deafness, and genetic counseling is recommended for management and family planning.
Are there any risks associated with the test?
Risks are minimal, such as minor bruising from blood draw, but there may be emotional impacts from genetic results.
