Understanding Your Results

Results indicate the presence or absence of pathogenic variants in the NXF5 gene. A positive result confirms a genetic cause for non-syndromic mental retardation.
Positive: Pathogenic variant found, indicating genetic cause
Negative: No pathogenic variants detected, other causes may be considered
Variant of Uncertain Significance (VUS): Further testing or family studies recommended
⚠️ When to Consult a Doctor:

Consult a geneticist or neurologist if symptoms persist or if positive results are obtained for management and counseling.

Limitations

  • ⚠May not detect all genetic causes of mental retardation
  • ⚠Results require clinical correlation
  • ⚠Cannot predict disease severity in all cases

Risks & Considerations

  • ●Minimal risk from blood draw: bruising, infection
  • ●No significant genetic risks from testing itself

Interfering Factors

  • ●Contaminated DNA samples
