PRNP Gene Fatal Familial Insomnia NGS Genetic DNA Test
Comprehensive Genetic Analysis for Rare Neurological Sleep Disorder
The PRNP Gene Fatal Familial Insomnia NGS Genetic DNA Test represents a breakthrough in neurological genetic testing, providing definitive diagnosis for one of medicine’s most challenging conditions. Fatal familial insomnia (FFI) is an extremely rare autosomal dominant prion disease characterized by progressive insomnia, autonomic dysfunction, and motor disturbances that ultimately lead to complete sleep loss and fatal outcomes.
What This Advanced Genetic Test Detects
Our comprehensive NGS-based analysis specifically targets the PRNP (prion protein) gene located on chromosome 20, focusing on the D178N mutation that is pathognomonic for fatal familial insomnia. The test examines:
- Complete PRNP gene sequencing using next-generation sequencing technology
- Detection of the specific D178N mutation associated with FFI
- Identification of codon 129 polymorphism status (methionine/methionine genotype)
- Comprehensive analysis of all coding regions and splice sites
- Detection of other PRNP mutations that may cause similar prion diseases
Who Should Consider This Genetic Test
This test is particularly recommended for individuals experiencing:
- Progressive, treatment-resistant insomnia developing in adulthood
- Family history of fatal familial insomnia or unexplained neurological disorders
- Autonomic nervous system dysfunction including hypertension, tachycardia, and hyperhidrosis
- Motor disturbances such as ataxia, myoclonus, or spasticity
- Cognitive decline or memory impairment accompanying sleep disturbances
- Unexplained weight loss and endocrine abnormalities with sleep issues
- Individuals from families with known PRNP gene mutations
Significant Benefits of Early Genetic Testing
Undergoing PRNP genetic testing provides numerous critical advantages:
- Definitive Diagnosis: Eliminates diagnostic uncertainty and enables accurate disease identification
- Family Planning Guidance: Provides essential information for genetic counseling and reproductive decisions
- Early Intervention: Allows for symptom management and supportive care planning
- Genetic Counseling: Enables comprehensive family risk assessment and pedigree analysis
- Research Contribution: Participation in ongoing studies for rare neurological disorders
- Peace of Mind: Resolves diagnostic uncertainty for affected individuals and at-risk family members
Understanding Your Genetic Test Results
Our comprehensive genetic counseling team will help you interpret your results:
- Positive Result: Indicates presence of the D178N mutation with methionine at codon 129, confirming fatal familial insomnia diagnosis
- Negative Result: No pathogenic PRNP mutations detected, significantly reducing FFI risk
- Variant of Uncertain Significance: Rare genetic changes requiring further clinical correlation
- Carrier Status: Important information for family members and genetic inheritance patterns
All positive results include detailed genetic counseling sessions to discuss implications, family testing recommendations, and management strategies.
