Understanding Your Results

Results from the GRIA3 Gene NGS Test indicate the presence or absence of mutations in the GRIA3 gene. A positive result confirms a genetic basis for intellectual disability, guiding further management.
📊

Confirms diagnosis of GRIA3-related X-linked mental retardation type 94. Genetic counseling and management plans should be initiated.

Result type: Pathogenic variant detected

📊

Suggests that symptoms may be due to other genetic or environmental factors. Further evaluation is recommended.

Result type: No pathogenic variant detected

📊

Requires additional testing and family studies for clarification. Clinical correlation is essential.

Result type: Variant of uncertain significance

⚠️ When to Consult a Doctor:

Consult a neurologist or geneticist immediately if results indicate a pathogenic variant, for management planning. Also, seek consultation if symptoms worsen or new symptoms arise.

Limitations

  • ⚠May not detect all possible mutations or structural variants
  • ⚠Requires genetic counseling for interpretation
  • ⚠Results should be correlated with clinical findings
  • ⚠Test does not rule out other genetic or environmental causes of intellectual disability

Risks & Considerations

  • ●Minimal risk from blood draw: slight pain, bruising, or infection
  • ●Psychological impact of genetic results
  • ●Potential for uncertain results requiring further testing

Interfering Factors

  • ●Sample contamination
  • ●Degraded DNA quality
  • ●Inadequate sample volume
  • ●Recent blood transfusion affecting DNA purity
