Sample Collection
No fasting is required. A genetic counselling session may be requested to draw a pedigree chart of family members affected with PCDH11X gene associated dyslexia. Please carry clinical history and any previous test records.
Method: Blood draw / FTA card blood spot / Extracted DNA submission
Laboratory Analysis
A small blood sample is collected by venipuncture, or one drop of blood is placed on an FTA card, or an extracted DNA sample is submitted for analysis.
Report Delivery
No special precautions are needed. The sample is transported to the laboratory at ambient room temperature. Reports are generally delivered in 3 to 4 weeks.
Timeline: Samples are usually processed within 3 to 4 weeks after the sample reaches the laboratory.

About This Test
Who Should Get This Test
The purpose of this NGS genetic test is to analyze the PCDH11X gene and identify mutations or variations that may be associated with dyslexia. It can support a clinical diagnosis, provide information for family counselling, and help guide personalized remedial and therapeutic approaches.
How to Prepare
- No fasting is required for this test.
- For blood sample collection, use an EDTA tube and label it clearly with patient details.
- For FTA card, apply one drop of blood to the card and air dry completely before packaging.
- For extracted DNA, submit the DNA aliquot in a sterile, labeled vial.
- Inform the laboratory about any prior genetic testing.
Doctor's Notes
Reviewed by Dr SULOCHANA HEMCHANDRA HOLLA — MBBS, MD (Medical Genetics) · Reg. No. 8532
"A neurological assessment can help distinguish dyslexia from other causes of learning difficulty. Genetic testing adds valuable data when a strong family history or persistent neurodevelopmental concern is present."

- Clotted blood sample
- Contaminated FTA card
- Insufficient DNA quantity or quality
Understanding Your Results
Pathogenic or likely pathogenic variant detected
Identifies a genetic factor that may contribute to dyslexia. A clinical correlation and genetic counselling are strongly recommended.
Variant of uncertain significance (VUS) detected
Insufficient evidence is available to determine clinical significance. Additional family studies or genetic testing may be recommended.
No pathogenic variant detected
Does not exclude dyslexia. Other genetic, environmental, or educational factors may be responsible for the symptoms.
If a child or adult has persistent reading, writing, spelling, or phonological processing difficulties, or has a family history of dyslexia, consult a neurologist, paediatrician, or clinical geneticist for a comprehensive evaluation.
Limitations
- ⚠This test analyzes the PCDH11X gene only; other genes associated with dyslexia are not covered.
- ⚠A genetic result alone is not sufficient to diagnose dyslexia.
- ⚠A variant of uncertain significance may be reported; the clinical meaning is not always clear.
- ⚠A negative result does not exclude a genetic or non-genetic cause of dyslexia.
Risks & Considerations
- ●Minimal risk of pain, bruising, or bleeding at the blood draw site
- ●Rare risk of infection from venipuncture
- ●No risk associated with FTA card collection
Interfering Factors
- ●Insufficient DNA amount due to poor blood spot application
- ●Sample contamination from foreign DNA
- ●Poor DNA quality or degradation
- ●Improper labeling or documentation
