Customization of Diagnostic Panels

FLEX panels

All of our >220 panels can be customized by adding any of our >4,000 clinically relevant genes or by removing genes from the selected panel. Customized panels are called FLEX Panels.

The panels can be customized by:

  • Adding up to 200 genes from a list of >4000 clinically relevant genes from any medical specialty related to the patient’s phenotype
  • Removing as many genes as desired (until a minimum of 2 remains).

Customized panels can be saved and named by each user in our online portal Nucleus. All saved panels will be stored in the “My Saved FLEX panels” list for later use. The name of the saved panel will be visible only to the user.

The customization of panels is intended to bring value to the patient’s diagnosis and current clinical presentation/phenotype.  The customized test is not intended for carrier testing, predictive testing or general population screening. 

Customized panels can only be ordered through our Nucleus ordering portal. Simply choose the panel you wish to order and select the ”Order/Customize in Nucleus” tab from the panel specific page.

Flex panels will be priced based on the number of genes included. The number of genes determine the size of the panel:

  • Small = 2-25 genes
  • Medium = 26-125 genes
  • Large = >125 genes

For our pricing, please visit our pricing page. If you have any questions, please contact us.

Turnaround Time

The great majority of tests are completed within 28 days.

  • Panel-specific genes with reduced performance are noted with a # and/or an * on the panel content pages.
  • Please note that customized panels may lead to reduced diagnostic utility and the intended use may change in a case where gene(s) relevant for the patient’s phenotype are removed. Any changes made to a panel through customization are the responsibility of the ordering clinician.
  • If individual mtDNA genes are added to a panel instead of the entire mitochondrial genome, the noncoding region of the mitochondrial genome will not be included, and some deletions might not be detected.
