Medical Exome: Clinical Exome Sequencing, Additional Family Member
Test Code: 1738
Turnaround time: 12 weeks

Traditionally there are two options when ordering exome sequencing. One can analyze only the affected individual (proband only) or a family trio (typically the affected person and his/her parents). Analyzing trios has shown to increase the diagnostic yield of exome sequencing by providing deeper insights into the proband’s findings. CEN4GEN also offers an additional family member option to further increase the clinical efficacy of its exome sequencing. This test allows clinicians to submit an additional child or family member (affected or unaffected) to assist better diagnosing findings that have unclear significance.

The sequencing design of the Medical Exome analysis provides >97% coverage of 22,000 genes, with a mean read depth of 100X. Of the ~4600 disease-associated genes analyzed, 3000 have 100% coverage (≥20X) of all exons; twice the number of genes with complete coverage offered by competitors, making it the most comprehensive exome sequencing test available, with highest coverage.

Please note this test should be ordered at the same time as the “Medical Exome: Clinical Exome Sequencing, Family Trios” (test code: 7785).

The Medical Exome analysis test is indicated when there is a suspicion of a genetic etiology contributing to the proband’s manifestations.
