Suggested Custom Slice – VACTERL Association
Use
This Custom Slice test is designed for individuals suspected of having VACTERL association (vertebral defects, anal atresia, cardiac defects, tracheoesophageal fistula, renal anomalies, and limb abnormalities). It enables targeted genomic analysis by sequencing the exome and restricting analysis to a provider-specified gene list relevant to VACTERL phenotypes. This approach can help detect variants across relevant genes when standard gene panels are not available or insufficient.
Special Instructions
Providers must submit a custom gene list via the online Slice Tool. GeneDx reviews and approves the list (typically within 3 business days), and provides a tracking number required on the requisition and sample label. The analytic pipeline sequences the exome but limits analysis to those genes; incidental secondary findings are not reported unless in the submitted gene list.
Limitations
The test analyzes only the genes specified by the provider; variants in other genes—even if medically significant—will not be identified. Secondary findings per ACMG guidelines (e.g., in XomeDx® or XomeDx® Plus) are excluded unless included in the submitted gene list. The test is performed on the proband only; family member inclusion depends on available options and may incur additional fees.
