MLPA probes hybridize to target regions of the CFTR gene and are amplified by multiplex PCR. The amplification products are analyzed by capillary electrophoresis and copy numbers for these CFTR target regions are generated.
This test is used to detect the presence of CFTR (OMIM:602421) deletions and duplications. CFTR gene deletion and duplication analysis can be performed on patients with only one or no CFTR mutations detected by sequence analysis but have a clinical presentation consistent with CFTR-related disorders or on relatives of a patient with a known CFTR deletion/duplication mutation. Currently the deletion and duplication detections rates in different population groups are not known.

Collect specimen in a lavender top tube. Send intact specimen within 24 hours if stored at room temperature or within 5 days if stored refrigerated. Include the patient's family history, pedigree, and ethnicity on the test requisition. Obtaining informed consent from the patient prior to genetic testing is strongly recommended. If desired, a UMHS Request and Consent for Genetic Testing form can be obtained from the MMGL Molecular Genetics Laboratory by contacting the MLabs Client Services Center at 800-862-7284 or online at https://mlabs.umich.edu/sites/default/files/2020-01/file/pci-mmgl_infor….
