Clinical Diagnostic Exome Requirements

The following requisition forms are required for Clinical Diagnostic Exome™:

Families will undergo a detailed informed consent process with their clinical genetic counselor. As part of the consent process, an overview and explanation of exome sequencing and the limitations are discussed with the patient as well as options for results blinding. The patient may choose whether to be given results information regarding recessive disorders, late-onset disease and cancer pre-disposition syndromes.

Family History (Pedigree) & Clinical History Information

Because of the complex nature of exome sequencing, it is essential that Ambry is informed of the complete clinical picture. Providing more details regarding the phenotype can only improve the interpretation of results. 

The following items are required for test processing:

  • Detailed patient clinical history (can be in the form of a clinic note)
  • A copy of the family history (pedigree)
  • A copy of previous genetic test results
