INDICATION-SPECIFIC GENE PANEL TESTING
- This panel includes both full sequencing andhigh resolution deletion/duplication analysis.
- Detection abilitiy is limited to the genes specified; it does not provide whole genome analysis.
- Gene panels are a more cost-effective approach than single gene testing to confirm or establish a diagnosis.
DISORDERS INCLUDED IN THIS PANEL:
INDICATIONS FOR TESTING:
- Facial features such as proptosis (bulging eyes), ptosis, widely spaced eyes, flattened midface, temporal bossing
- Syndactyly, clinodactyly, broad toes, broad thumbs
- Short stature or shortened long bones
- Palatal abnormalities (cleft or high palate)
- Bone fusions, especially carpal, tarsal, and radioulnar synostosis
- Developmental delay, hearing loss, or vision concerns in a person suspected to have craniosynostosis or skeletal dysplasia
OUR LABORATORY'S RECOMMENDED TESTING STRATEGY
Comprehensive Testing: Connective Tissue Disorders
Next Generation Sequencing Panel with reflex to Deletion/Duplication Analysis
NOTE: Each of the tests recommended for comprehensive testing can be ordered individually if the comprehensive package is not desired. For questions regarding testing strategies for your patient, please call our laboratory at 402-559-5070 and ask to speak with a laboratory genetic counselor.
Chromosomal abnormalities, including microdeletions and microduplications, are found in at least 15% of children with craniosynostosis including some children with isolated or single-suture craniosynostosis*. High Density SNP Microarray can be ordered simultaneously or in a tiered fashion to assess for these copy number changes.

For questions regarding the usefulness of complementary testing for your patient, please call our laboratory at 402-559-5070 and ask to speak with a laboratory genetic counselor.
