The exome constitutes about 2%-3% of the genome, There are about 180,000 exons in the over 20,000 genes in the human genome, WES  generally allows for simultaneous analysis of all exons in one test, WES  will analyze close to 95% of the exons, WES is usually considered for individuals with rare diseases or syndrome for whom testing of specific potentially disease causing genes have not identified any disease causing gene mutations, WES will not detect all types of genetic changes in the exome, so there are limitations, Costs tend to be lower than whole genome sequencing (WGS), The routine use of prenatal sequencing is not recommended, including cases where fetal, Clinical validation data are currently insufficient and prospective studies are required to determine clinical utility and risks vs harms, Fetal anomalies or a single major anomaly suggestive of a genetic disorder, No microarray results is available but the fetus exhibits anomalies strongly suggesting of a single gene disorder, Previous undiagnosed fetus (or child) from either parent, with single or multiple anomalies suspicious for a genetic syndrome that has now recurred in the current pregnancy, Karyotype and microarray in the current pregnancy have not yielded a diagnosis, Make every effort to obtain a sample from the current pregnancy or previously affected offspring, If samples are unavailable from previously affected offspring or the current pregnancy, consider offering parents sequencing to determine if they may be carriers for an, History of recurrent stillbirths with negative karyotype and/or microarray, where the fetus is exhibiting a similar pattern of anomalies, Fetus with ultrasound anomalies and no results from CMA and karyotype, In the case of concern related to a specific phenotype or disorder, start with more targeted molecular testing  (single-gene test or gene panel), Do not use WES for other indications such as soft markers for Down syndrome or recurrent pregnancy loss, WES analysis will generally require a blood sample, Results from WES will not always yield definitive, actionable results that confirm a diagnosis, Findings may indicate a Variant of Uncertain Significance (, WES testing may often be most informative when an individual’s family members are also tested or willing to be tested to clarify result interpretation, Genetic counseling is recommended pre and post WES analysis, Thorough informed consent process is imperative given the potential for results that may or may not be definitive, Accurate, comprehensive clinical information | Successful interpretation of variants dependent on accuracy of phenotype, Trios: Samples from mother, father and fetus that can be used for molecular analysis, Variants that are likely and known pathogenic, Report highly penetrant pathogenic variants that are known to cause moderate to severe childhood onset disorders, Do not report if there is no known fetal or childhood phenotype, even if the variant involves a severe disorder, Not specific to WES, but especially with trio samples, it may come to light that a parent is not the biologic parent (e.g, mistaken paternity), Critical that this possibility be included in pretest counseling and laboratories should have policies in place to deal with this issue, It may be reasonable to reanalyze results after 12 months (or sooner at the discretion of the lab) if there is no definitive answer  because, Children may manifest new signs and symptoms that further refine the phenotype, New genetic discoveries are being uploaded daily to databases and may contribute to a final molecular diagnosis.
