Partial sequencing is performed for AKAP9 (exon 18), APOB (556 bp of exon 26) and SHOC2 (exon 2).
When ordering please specify the name of the gene(s) to be sequenced. On ETRF, use Relevant Clinical Indication field to specify.
For all tests, specimens must be accompanied by a completed consent form. See sample physician office consent form: Consent for Genetic Testing (in Related Documents). In cases in which a known mutation can be documented, the physician may prefer to order test 451382, Mutation-specific Sequencing, Whole Blood (link in Related Information). Please call customer service at 866-647-0735 before submitting specimens for family testing (ie, known mutations).
Expected Turnaround Time
16 - 35 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

This analysis does not rule out germline mosaicism, the presence of large chromosomal aberrations (including deletions, insertions, and rearrangments), mutations in regions or genes not included in this test, and possible inter/intragenic interactions between sequence variants. False-positive or false-negative results may occur for reasons that include genetic variants, blood transfusions, bone marrow transplantation, mislabeled specimens, or erroneous representation of family relationships.
This test was developed, and its performance characteristics determined, by LabCorp. It has not been cleared or approved by the US Food and Drug Administration (FDA).
Mutation analysis is performed using the Agilent Sure Select XT® enrichment method and the Illumina® next-generation sequencing platform. Regions of interest include all exons and splice junctions for each gene and limited regions for the following: SHOC2 (exon 2), APOB (556bp of exon 26), and AKAP9 (exon 18). Sequencing reads are aligned with the hg19 build of the human genome reference sequence. Analytical sensitivity is based on the depth of coverage across the regions of gene interest and is provided separately for each gene. Greater than 98% of target bases are synonymous variants not previously recorded at greater than or equal to 20x coverage. Sanger sequencing is used to confirm mutation identity and analyze regions with low coverage. Variants are reported using numbering and nomenclature recommended by the Human Genome Variation Society (HGVS: http://hgvs.org/). Variants known to be benign and synonymous variants not previously recorded in our internal variant databases are not reported.
