Step 3

Report Delivery

The sample is processed and sent for NGS analysis. Post-test, genetic counseling is advised to discuss results and implications.

Timeline: 3-4 weeks from sample collection

Patient Instructions

1
Before the Test:Provide clinical history and undergo genetic counseling to document family history.
2
During the Test:Blood sample collection using standard procedures; minimal discomfort expected.
3
After the Test:Monitor the collection site for bruising; await results in 3-4 weeks.

Understanding Your Results

Results from the MYH8 Gene Arthrogryposis NGS Genetic Test indicate the presence or absence of pathogenic mutations in the MYH8 gene, which are associated with distal type 7 arthrogryposis.
📊

No pathogenic variants detected

Normal result; no MYH8 gene mutations identified. Clinical correlation is advised.

📊

Pathogenic variant detected

Confirms diagnosis of distal arthrogryposis type 7. Genetic counseling and family testing recommended.

📊

Variant of uncertain significance

Further testing or family studies may be needed for clarification.

⚠️ When to Consult a Doctor:

If symptoms such as joint stiffness, abnormal finger/toe positioning, or difficulty with motor tasks persist, or if genetic testing results indicate a mutation, consult a geneticist or specialist for management.

Limitations

  • ⚠May not detect all possible mutations in the MYH8 gene
  • ⚠Results should be interpreted in conjunction with clinical findings
  • ⚠Genetic counseling is recommended for result interpretation

Risks & Considerations

  • ●Minor bruising or discomfort at the blood draw site
  • ●Rare risk of infection
  • ●Emotional impact from genetic findings; counseling is available

Interfering Factors

  • ●Degraded or insufficient DNA sample
  • ●Contamination during sample collection
  • ●Recent blood transfusions may affect DNA analysis
