Sponsored, no-charge genetic testing for individuals suspected of having long-chain fatty acid oxidation disorders.

Program eligibility

This program is available to patients in the US and Canada who meet at least one of the following criteria:

  • Has a completed UltraCare Start Form for LC-FAOD (if available, please provide a copy of abnormal biochemical confirmatory labs)

  • Is suspected of having or has been diagnosed with a long-chain fatty acid oxidation disorder AND a plasma acylcarnitine test, has either been performed (regardless of result, abnormal or normal) or has been ordered.

Providing a copy of plasma acylcarnitines results, or any other confirmatory tests, when available, is strongly encouraged. These results are helpful for variant interpretation and in some cases can make a difference for the final interpretation of the variant.

This program offers the Invitae Fatty Acid Oxidation Defects Panel to test for variants in 24 genes:


These genes are known to be associated with beta-oxidation of fatty acids, carnitine shuttle, carnitine transport, ketogenesis, and conditions which may cause similar abnormal profiles on plasma acylcarnitine analysis.
