Testing Algorithm
For prenatal specimens only: If amniotic fluid (nonconfluent cultured cells) is received, amniotic fluid culture will be added and charged separately. If chorionic villus specimen (nonconfluent cultured cells) is received, fibroblast culture will be added and charged separately. For any prenatal specimen that is received, maternal cell contamination studies will be added.
Any FMTT orders for a variant that was detected by whole exome sequencing (WES) or next-generation sequencing (NGS) large panel assays require a proband sample that has been previously run on these assays at Mayo Medical Laboratories. Please contact the laboratory to determine whether adequate DNA is available in the laboratory or if a new proband sample is required.

Clinical Information
This test is available to test for the presence of 1 or more mutations previously identified in a family member. Targeted testing is used for diagnostic or predictive testing in cases in which mutations have been previously identified in an affected family member. Targeted testing is available for a specific subset of genes only.

Testing may be delayed if the required documentation is not received (ie, patient information sheet).
Reference Values
An interpretive report will be provided.
Cautions
Clinical Correlations:
The identification of a disease-causing mutation in an affected family member is necessary before predictive testing for other family members can be performed. If a familial mutation has not been previously identified, contact Mayo Medical Laboratories at 800-533-1710 to discuss testing options.
Test results should be interpreted in the context of clinical findings, family history, and other laboratory testing. Misinterpretation of results may occur if the information provided is inaccurate or incomplete.
Technical Limitations:
Rare polymorphisms exist that could lead to false-negative or false-positive results. If results obtained do not match the clinical findings, additional testing should be considered.
A previous bone marrow transplant from an allogenic donor will interfere with testing. Call Mayo Medical Laboratories for instructions for testing patients who have received a bone marrow transplant.
Analysis is performed for the familial mutations provided only. This assay does not rule out the presence of other mutations within this gene or within other genes that may be associated with hereditary cancer syndromes.
In addition to disease-related probes, the multiplex ligation-dependent probe amplification technique utilizes probes localized to other chromosomal regions as internal controls. In certain circumstances, these control probes may detect other diseases or conditions for which this test was not specifically intended. Results of the control probes are not normally reported. However, in cases where clinically relevant information is identified, the ordering physician will be informed of the result and provided with recommendations for any appropriate follow-up testing.
