List of diseases covered by the panel

Lab method: NGS panel with CNV analysis

TAT: 6-9 weeks

Specimen requirements: 2-4 ml of blood with anticoagulant EDTA

1 µg DNA in TE, AE or pure sterile water at 100-250 ng/µl
The A260/A280 ratio should be 1.8-2.0. DNA sample should be run on an agarose gel as a single band, showing no degradation, alongside with a quantitative DNA marker.

Indications for genetic testing:

  1. Confirmation of clinical diagnosis
  2. Carrier testing for at-risk family members
  3. Genetic counseling

Stickler syndrome is a group of hereditary conditions affecting connective tissue. Stickler syndrome is characterized by ocular findings, distinctive facial abnormalities, hearing loss, skeletal abnormalities, and joint problems.

Eye findings may include high myopia, cataract, vitreoretinal or chorioretinal degeneration, and retinal detachment. Hearing loss can be both conductive and sensorineural. Affected individuals have a characteristic flattened facial appearance caused by midfacial underdevelopment and cleft palate.

Stickler syndrome is inherited in an autosomal dominant or autosomal recessive manner. Stickler syndrome affects approximately 7,500 to 9,000 newborns.
