Test ID: FMTT    
Familial Mutation, Targeted Testing

Diagnostic or predictive testing for specific conditions when 1 or more mutations have been identified in a family member

                   

Carrier screening for individuals at risk for having a mutation that was previously identified in a family member

Documentation of the specific familial mutations is required and must be provided with the specimen in order to perform this test. Consultation with the laboratory is required prior to ordering this test.

 

Note: analysis of the area surrounding the familial variant may be required in the performance of this assay, which could result in identification of additional variants. Contact the laboratory at 800-533-1710 with any questions regarding assay performance.

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.

 

Testing for variants detected by WES or large panels: 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 tested at Mayo Clinic Laboratories. Contact the laboratory to determine whether adequate DNA is available in the laboratory or if a new proband sample is required.
