LFNG Gene Spondylocostal Dysostosis Autosomal Recessive Type 3 NGS Genetic DNA Test
Understanding Spondylocostal Dysostosis Type 3
Spondylocostal dysostosis type 3 is a rare genetic disorder characterized by severe malformations of the spine and ribs, resulting from mutations in the LFNG (Lunatic Fringe) gene. This condition falls under the broader category of skeletal dysplasias and represents a significant challenge in pediatric orthopedics and genetics. The LFNG gene plays a crucial role in the Notch signaling pathway, which is essential for proper segmentation and patterning of the vertebral column during embryonic development.
What This Advanced Genetic Test Detects
Our comprehensive NGS (Next-Generation Sequencing) genetic test specifically targets the LFNG gene to identify pathogenic variants responsible for spondylocostal dysostosis type 3. The test examines:
- Complete coding regions of the LFNG gene
- Exon-intron boundaries for splice site mutations
- Known pathogenic variants associated with spinal malformations
- Novel mutations that may impact protein function
- Autosomal recessive inheritance patterns
Clinical Indications and Who Should Consider Testing
This genetic test is recommended for individuals presenting with:
- Congenital vertebral segmentation defects
- Multiple rib abnormalities and fusion
- Short trunk dwarfism with normal limb length
- Restrictive lung disease due to thoracic insufficiency
- Family history of spinal malformations
- Unexplained neonatal respiratory distress
- Planned pregnancy with family history of skeletal disorders
Key Benefits of LFNG Genetic Testing
Undergoing this specialized genetic analysis provides numerous advantages:
- Accurate Diagnosis: Confirms the specific genetic cause of spinal abnormalities
- Family Planning: Enables informed reproductive decisions for at-risk couples
- Medical Management: Guides appropriate surgical and therapeutic interventions
- Prognostic Information: Helps predict disease progression and potential complications
- Genetic Counseling: Provides basis for comprehensive family genetic assessment
- Research Contribution: Advances understanding of rare skeletal disorders
Understanding Your Test Results
Our genetic specialists provide detailed interpretation of your results:
- Positive Result: Identifies pathogenic LFNG mutations confirming diagnosis
- Negative Result: No mutations detected, though other genetic causes may exist
- Variant of Uncertain Significance: Requires additional family studies for clarification
- Carrier Status: Identifies individuals with one mutated copy of the gene
All results include comprehensive genetic counseling to ensure proper understanding and next steps.
