EFNB1 Gene Craniofrontonasal Syndrome NGS Genetic DNA Test
Comprehensive Genetic Testing for Craniofrontonasal Syndrome
The EFNB1 Gene Craniofrontonasal Syndrome NGS Genetic DNA Test represents a cutting-edge diagnostic approach for identifying mutations in the EFNB1 gene, which is responsible for Craniofrontonasal Syndrome (CFNS). This rare X-linked genetic disorder primarily affects craniofacial development and requires precise genetic confirmation for accurate diagnosis and management.
What This Test Measures and Detects
Our advanced Next-Generation Sequencing (NGS) technology comprehensively analyzes the EFNB1 gene to identify pathogenic variants, including:
- Point mutations and single nucleotide variants
- Small insertions and deletions
- Copy number variations affecting the EFNB1 gene
- Missense, nonsense, and frameshift mutations
- Splice site alterations affecting protein function
The EFNB1 gene encodes ephrin-B1, a critical protein involved in cell signaling during embryonic development, particularly in neural crest cell migration and craniofacial patterning.
Who Should Consider This Genetic Test
This test is recommended for individuals presenting with the following clinical features:
- Craniosynostosis (premature fusion of skull sutures)
- Hypertelorism (widely spaced eyes)
- Frontonasal dysplasia with bifid nasal tip
- Cleft lip and/or palate abnormalities
- Developmental delays and intellectual disability
- Distinctive facial features including downslanting palpebral fissures
- Family history of craniofacial abnormalities
- Unexplained syndromic features in pediatric patients
Clinical Benefits of EFNB1 Genetic Testing
Undergoing EFNB1 genetic testing provides numerous clinical advantages:
- Accurate Diagnosis: Confirms Craniofrontonasal Syndrome with molecular precision
- Family Planning Guidance: Enables informed reproductive decisions and genetic counseling
- Personalized Treatment: Guides appropriate surgical interventions and management strategies
- Early Intervention: Facilitates timely multidisciplinary care coordination
- Genetic Counseling: Provides risk assessment for family members and future pregnancies
- Differential Diagnosis: Helps distinguish CFNS from other craniofacial syndromes
Understanding Your Test Results
Our comprehensive genetic report includes detailed interpretation of your results:
- Positive Result: Identifies a pathogenic EFNB1 mutation confirming Craniofrontonasal Syndrome diagnosis
- Negative Result: No EFNB1 mutation detected, though clinical correlation remains essential
- Variant of Uncertain Significance: Identifies genetic changes requiring further clinical evaluation
- Carrier Status: Determines inheritance patterns and family member risks
All results are accompanied by detailed genetic counseling recommendations and clinical management guidance from our expert team.
