Normal

No pathogenic variants detected in the CASK gene; FG syndrome type 4 is unlikely.

📊

Abnormal

Pathogenic variant detected; consistent with FG syndrome type 4, requiring clinical correlation.

📊

Uncertain

Variant of uncertain significance detected; further testing or family studies may be recommended.

⚠️ When to Consult a Doctor:

If symptoms of FG syndrome type 4 are present, if results indicate a mutation, or for guidance on management and family planning, consult a geneticist or neurologist.

Limitations

  • ⚠May not detect all types of mutations in the CASK gene
  • ⚠Does not rule out other genetic disorders
  • ⚠Results should be interpreted in clinical context
  • ⚠Variant of uncertain significance may require further testing

Risks & Considerations

  • ●Minimal risk from blood draw, such as bruising, bleeding, or infection at the puncture site

Interfering Factors
