CLDN19 Gene Hypomagnesemia Type 5 NGS Genetic DNA Test
Comprehensive Genetic Testing for Kidney Magnesium Disorders
The CLDN19 Gene Hypomagnesemia Type 5 NGS Genetic DNA Test represents a breakthrough in genetic diagnostics for inherited kidney disorders. This advanced test specifically targets mutations in the CLDN19 gene, which plays a crucial role in maintaining proper magnesium balance and kidney function. Hypomagnesemia type 5, also known as familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC), is a rare autosomal recessive disorder that can lead to severe kidney complications if left undiagnosed.
What Does This Test Measure?
This comprehensive genetic analysis utilizes next-generation sequencing (NGS) technology to examine the complete coding region of the CLDN19 gene. The test specifically detects:
- Point mutations, deletions, and insertions in the CLDN19 gene
- Genetic variations affecting claudin-19 protein function
- Mutations responsible for impaired renal magnesium reabsorption
- Genetic markers associated with progressive kidney damage
- Inheritance patterns for family planning purposes
Who Should Consider This Test?
This genetic test is particularly important for individuals experiencing:
- Unexplained persistent hypomagnesemia (low magnesium levels)
- Recurrent kidney stones or nephrocalcinosis
- Family history of kidney disorders or magnesium deficiency
- Vision problems including severe myopia or macular coloboma
- Children with failure to thrive and developmental delays
- Individuals with elevated calcium levels in urine (hypercalciuria)
- Patients with progressive kidney dysfunction of unknown cause
Clinical Benefits of Testing
Early genetic diagnosis through CLDN19 testing provides numerous clinical advantages:
- Early Intervention: Enables proactive management before irreversible kidney damage occurs
- Personalized Treatment: Guides targeted magnesium supplementation and dietary modifications
- Family Planning: Provides crucial information for genetic counseling and reproductive decisions
- Disease Monitoring: Establishes baseline for ongoing kidney function surveillance
- Vision Care: Facilitates early ophthalmological interventions for associated eye conditions
- Preventive Care: Helps prevent complications like end-stage renal disease
Understanding Your Test Results
Your genetic test results will be carefully interpreted by our expert genetic counselors and physicians:
- Positive Result: Indicates the presence of CLDN19 gene mutations, confirming diagnosis of hypomagnesemia type 5
- Negative Result: Suggests absence of detectable CLDN19 mutations, though other genetic causes may need investigation
- Variant of Uncertain Significance: Identifies genetic changes whose clinical significance requires further evaluation
- Carrier Status: Determines if you carry one copy of the mutated gene without showing symptoms
