RB1 Gene Deletion and Duplication Detection for Retinoblastoma
Understanding RB1 Gene Testing for Retinoblastoma
The RB1 Gene Deletion and Duplication Detection test represents a critical advancement in genetic diagnostics for Retinoblastoma, a rare but serious childhood eye cancer. This specialized molecular analysis focuses on identifying specific genetic abnormalities within the RB1 tumor suppressor gene, which plays a fundamental role in regulating cell growth and preventing tumor formation in retinal cells.
Retinoblastoma affects approximately 1 in 15,000-20,000 live births, with about 40% of cases being hereditary. The RB1 gene, located on chromosome 13, serves as the primary genetic gatekeeper for retinal cell development. When mutations, deletions, or duplications occur in this gene, the normal cell cycle control mechanisms fail, leading to uncontrolled cell proliferation and tumor formation in the retina.
What Does the RB1 Gene Test Detect?
Our comprehensive RB1 gene analysis specifically targets:
- Complete and partial gene deletions affecting RB1 functionality
- Gene duplications that may disrupt normal protein production
- Copy number variations within the RB1 gene region
- Structural abnormalities impacting gene expression
The test employs advanced Multiplex Ligation-dependent Probe Amplification (MLPA) technology, which provides superior sensitivity and accuracy in detecting copy number variations compared to traditional sequencing methods alone. This approach ensures comprehensive coverage of the entire RB1 gene region, minimizing the risk of missed diagnoses.
Technical Methodology
Our MLPA-based testing protocol involves:
- DNA extraction from peripheral blood samples
- Specific probe hybridization to RB1 gene regions
- Amplification and quantification of target sequences
- Comparative analysis against reference samples
- Quality control verification at multiple stages
Who Should Consider RB1 Gene Testing?
This genetic test is particularly recommended for:
Children and Infants
- Infants with family history of Retinoblastoma
- Children showing early signs of leukocoria (white pupil reflex)
- Patients with strabismus or vision abnormalities
- Children with unexplained eye redness or swelling
At-Risk Families
- Parents with previous Retinoblastoma diagnosis
- Siblings of affected children
- Family members planning pregnancy with Retinoblastoma history
- Relatives of individuals with bilateral Retinoblastoma
Clinical Indications
- Unexplained vision changes in young children
- Abnormal retinal examinations
- Family planning considerations with genetic risk factors
- Prenatal genetic counseling requirements

Understanding Your Test Results
Positive Results Interpretation
A positive result indicating RB1 gene deletion or duplication suggests:
- Increased risk for Retinoblastoma development
- Need for regular ophthalmological examinations
- Potential hereditary transmission to offspring
- Consideration of genetic counseling for family members
Negative Results Interpretation
A negative result typically indicates:
- No detected RB1 gene abnormalities
- Significantly reduced hereditary risk
- Standard pediatric eye care recommendations
- Possible consideration of additional testing if clinical suspicion remains
Variant of Uncertain Significance
In rare cases, results may show:
- Genetic changes with unknown clinical impact
- Recommendation for family studies
- Continued clinical monitoring
- Potential reclassification with advancing research
