The clinical information provided by the ordering provider, including a description of the features, family history, and prior test results, is critical in the analysis of variants. We will also discuss the type of testing that is most useful and appropriate (i.e. (2016) J Pers Med 6 (2): (PMID: 27023617), Patiño et al. For more information please contact: (2015) Genetics In Medicine 17 (5):405-24 (PMID: 25741868), Sallevelt et al. Introduction. (2016) Hum. It is a powerful diagnostic tool, providing a definitive diagnosis in 20-50% of patients (Yang, et al. Family members can be tested for variants identified in the initial patient. What if extended family members want to be tested for a variant which was identified in a patient by XomeDx® testing? Some exons have low or no coverage because no probes have been designed or are unavailable for these regions. Form and fax it to the NYS Department of Health to obtain case-by-case permission
15:526(7573): 343-350 (PMID: 26469045), Retterer et al. Singleton AB. Ordering providers are encouraged to review the gene list and revise it by adding or subtracting desired genes. This test provides information in three primary health categories: personal health and reproductive risk. Across the exome, the average depth of coverage is 100-120x. Relative samples may be collected and shipped separately from the proband sample; however, relative specimens must be received within three weeks of receipt of the proband's sample. GeneDx will automatically perform a benefits investigation prior to testing. The XomeDxPrenatal Targeted fetal report will include medically relevant pathogenic or likely pathogenic variants in genes expected to be related to the reported fetal phenotype. (2016) Genet. (2014) Clin Pharmacol Ther. Hum Genet. Clinician identifies patient who could benefit from ES and cannot otherwise afford or have access to this testing. : (PMID: 27787503), Spear et al. Variant studies for the evaluation of a single VUS in a gene associated with an autosomal recessive disorder are rarely informative. If additional reports are requested for other affected family members, additional fees will apply. The positive rate is highest when a trio is submitted/analyzed, as the inclusion of parental data improves the ability to classify variants. Nebula Genomics 30x Whole Genome Sequencing. 207 Perry Parkway Gaithersburg, MD 20877
Through the GeneDx Odyssey Program, for every new disease-causing gene we publish this year, GeneDx will offer exome sequencing (ES) at no cost to a patient who meets clinical criteria and who cannot otherwise afford or have access to this testing. To check coverage of specific genes via exome sequencing, visit the XomeDx®Slice Tool. In addition,

We are committed to working with patients and offer flexible billing options. Wendy Chung, M.D. 58:931-50, Intong et al., 2012 ClinDermatol. In general, only a single report will be issued for the proband. How do I determine if a variant is eligible for the Clinical Genomics VTP? For such cases, GeneDx has established a Variant Testing Program (VTP). Applications will be reviewed to determine if the patient along with unaffected parents (or other appropriate relatives) may be eligible for no-charge WGS at GeneDx as part of our iHope Network collaboration (https://www.illumina.com/company/ihope.html). Approximately 98% of the targeted region of an affected individual's exome will be assessed with the XomeDx test at a minimum of 10x coverage, the minimum read depth necessary to detect a variant. carrier/targeted testing for any gene is automatically approved for relatives of

RI State License LCO00564 (2016) Pharmacoeconomics 34 (8):771-93 (PMID: 26984520), Qiao et al. Exons are captured and sequenced using massively parallel sequencing. Segregation studies involving genes with incomplete penetrance or variable age-of-onset are challenging, especially in unaffected individuals; therefore, VTP studies are less likely to be approved for such genes. GeneDx believes in responsible testing that is based on established medical guidelines. (2015) Obstetrics And Gynecology 125 (3):653-62 (PMID: 25730230), Gambin et al. Our CNV analysis via XomeDx® can identify: CNV analysis is limited or may not be possible in regions with reduced coverage, extreme GC- or AT-content, or significant homology to pseudogenes or segmental duplications. A written report including all clinically relevant, confirmed variants will be issued within approximately 2 weeks after the start of testing. Nat Rev Genet. Sci. Reanalysis is the process of reexamining the sequencing data generated from the XomeDx® test. ♦ Suggested gene lists, tailored to a specific test indication, are reviewed and updated periodically by GeneDx.

What additional testing can be requested? 91:259-61, Almaani et al., 2011 ActaDermVenereol. For any autosomal recessive gene, if one definitive mutation is found by XomeDxSlice sequencing, AND the gene fits the type of ichthyosis reported by the referring physician, capillary sequencing will be used to fill in sequence for exons that are not sufficiently covered (>10X) to find the second mutation. The GeneDx Clinical Genomics genetic counselors at 301-519-2100. Likely benign and benign variants, if present, are not routinely reported. If the variants detected in the proband are classified as pathogenic or likely pathogenic, family member testing can be ordered via Targeted Variant Testing (Site-Specific). Copyright, University of Washington, Seattle, 1997-2010. GeneDx does not conduct an independent analysis on relative samples. Therefore, there is no guarantee that participation in the VTP will lead to an updated classification of a VUS based on information from a single family, although cumulative data collected from multiple families over time may lead to a more definitive classification for a variant. Is exome sequencing via a trio better than a proband alone? XomeDx, or exome sequencing (ES), can be used to identify the underlying molecular basis of a genetic disorder in an affected individual and is best suited for patients who have a genetic condition that routine genetic testing has not been able to identify. ReproXpanded can be used to assess reproductive risk in couples and individuals who have already completed standard carrier screening.
