NAGLU Gene Mucopolysaccharidosis Type 3B NGS Genetic DNA Test

Comprehensive Genetic Testing for Sanfilippo Syndrome Type B

The NAGLU Gene Mucopolysaccharidosis Type 3B NGS Genetic DNA Test represents a breakthrough in genetic diagnostics for rare metabolic disorders. This advanced test utilizes next-generation sequencing technology to analyze the NAGLU gene, which plays a critical role in the breakdown of complex sugar molecules called glycosaminoglycans. When mutations occur in this gene, it leads to Mucopolysaccharidosis type 3B, also known as Sanfilippo syndrome type B – a progressive neurodegenerative disorder that primarily affects children.

What Does This Test Measure and Detect?

This comprehensive genetic test specifically targets and sequences the entire NAGLU gene to identify pathogenic variants that cause Sanfilippo syndrome type B. The test detects:

• Point mutations, insertions, and deletions in the NAGLU gene
• Missense, nonsense, and frameshift mutations
• Splice site variants affecting gene expression
• Compound heterozygous mutations
• Carrier status for family members

The NAGLU gene provides instructions for producing the enzyme alpha-N-acetylglucosaminidase, which is essential for breaking down heparan sulfate. When this enzyme is deficient due to genetic mutations, heparan sulfate accumulates in cells throughout the body, particularly in the central nervous system, leading to progressive neurological damage.

Who Should Consider This Genetic Test?

This test is recommended for individuals displaying symptoms consistent with Sanfilippo syndrome type B, including:

• Children experiencing developmental regression after initial normal development
• Patients with progressive neurological deterioration
• Individuals with behavioral problems including hyperactivity and aggression
• Children with sleep disturbances and coarse facial features
• Patients with mild skeletal abnormalities and joint stiffness
• Individuals with a family history of Sanfilippo syndrome
• Couples planning pregnancy with known family history of metabolic disorders

Key Benefits of NAGLU Genetic Testing

Undergoing this comprehensive genetic analysis provides numerous advantages for patients and families:

• Accurate Diagnosis: Confirms or rules out Sanfilippo syndrome type B with high precision
• Early Intervention: Enables timely management strategies and supportive care
• Family Planning: Provides crucial information for genetic counseling and reproductive decisions
• Treatment Guidance: Helps healthcare providers develop personalized care plans
• Prognostic Information: Offers insights into disease progression and expected outcomes
• Research Contribution: Contributes to ongoing studies and potential future therapies

Understanding Your Test Results

Our genetic counselors provide comprehensive interpretation of your results:

• Positive Result: Indicates pathogenic mutations in the NAGLU gene confirming Sanfilippo syndrome type B diagnosis
• Negative Result: Suggests no detectable mutations in the NAGLU gene, though clinical correlation is essential
• Variant of Uncertain Significance: Identifies genetic changes whose clinical significance requires further evaluation
• Carrier Status: Detects individuals with one mutated copy who may pass the condition to offspring

All results include detailed explanations and recommendations for next steps, including consultation with metabolic specialists and genetic counselors.
