Understanding Your Results

Results indicate the presence or absence of pathogenic variants in the ZDHHC9 gene. Positive results confirm a diagnosis of X-linked syndromic mental retardation, Raymond type.
Positive result: Mutation detected in the ZDHHC9 gene, supporting diagnosis.
Negative result: No pathogenic variants found; consider other differential diagnoses.
Variant of uncertain significance (VUS): Further evaluation and family studies may be needed.
⚠️ When to Consult a Doctor:

Consult a geneticist or neurologist if symptoms such as intellectual disability, delayed development, or seizures are present, especially with a family history of X-linked disorders.

Limitations

  • ⚠Test does not detect all possible genetic variants
  • ⚠Results may require confirmation with other methods
  • ⚠Limited to known mutations in the ZDHHC9 gene

Risks & Considerations

  • ●Minimal risk from blood draw (bruising, infection)
  • ●Psychological impact of genetic diagnosis

Interfering Factors
