MCAD - Unknown Mutation Detection by DNA Sequencing

Direct DNA sequencing is an accurate and proven technique for mutation detection in human genes. The Molecular Diagnostic Laboratory offers complete, cost-effective sequencing studies for all MCAD and CPTII mutation types, including substitutions, insertions and deletions.

Proof of definitive MCAD or CPTII diagnosis must be provided to the IMD for the sequencing test to be performed; evidence of proof may include:
• Acylcarnitine Profile whose results are consistent with MCAD or CPTII
• Enzyme assay results demonstrating reduced enzyme activity of MCAD or CPTII
• In-vitro probe for mitochondrial beta oxidation defects; probe results must demonstrate evidence for either MCAD or CPTII deficiency.

The sequencing will not be performed if the required information is not provided to the IMD upon sample submission.  Please contact Jeanna Firmin or Dr. Yang at 214-820-4533 for additional information.
