Test Code
252612


CPT Codes
81403

Includes
"All coding nucleotides of the specified gene(s), plus at least two and typically 20 nucleotides flanking each coding region.
"


Instructions
"This option is available when the mutation is known and can be documented by the ordering physician. If the mutation cannot be documented, please order test 252360.

For all Correlagen tests, specimens must be accompanied by a completed consent form. In the case of family tests (ie, known mutations), Correlagen requires the result report of the first patient tested in the family (the index case), if not performed at Correlagen. Other family members are subsequently tested for the specific mutation found in the first patient tested.

Methodology
"DNA sequencing "

Limitations
"This method does not reliably detect mosaic variants; large deletions; large duplications, inversions, or other rearrangements; or deep intronic variants. It may be affected by allele-dropout, it may not allow determination of the exact numbers of T/A or microsatellite repeats, and it does not allow any conclusion as to whether two heterozygous variants are present on the same or on different chromosome copies.

Results of this test are for investigational purposes only. The performance characteristics of this assay have been determined by LabCorp. The result should not be used as a diagnostic procedure without confirmation of the diagnosis by another medically established diagnostic product or procedure.
