Understanding Your Results

Results indicate the presence or absence of pathogenic variants in the WDR35 gene. Positive results confirm SRTD7 diagnosis, while negative results may require further testing.
📊

Pathogenic variant detected

Confirms diagnosis of SRTD7; genetic counseling recommended.

📊

No pathogenic variant detected

SRTD7 unlikely but clinical correlation needed; consider other genetic tests.

⚠️ When to Consult a Doctor:

Consult a doctor if symptoms such as short ribs, small chest, or polydactyly are present, or if family history suggests skeletal dysplasia.

Limitations

  • ⚠May not detect all genetic variants
  • ⚠Requires genetic counseling for interpretation
  • ⚠Results should be correlated with clinical findings

Risks & Considerations

  • ●Minimal risk from blood draw, such as bruising or infection
  • ●Psychological impact of genetic results

Interfering Factors

  • ●Sample contamination
  • ●Degraded DNA
  • ●Incorrect sample handling
