Patient/Member Information Patient Name: Subscriber Name: DOB: DOB Provider/Contact Information Ordering Provider: Contact Person: Subscriber Number: Phone: Fax: Genetic Test Information Name of test: Aortopathy Gene Panel Test Code: CPT code(s): ICD10 code(s): List price: Do you have a preferred clinical laboratory for genetic testing? __ NO (or not applicable) _ YES (provide preferred lab name): Please state the reason why testing should/must be performed at this laboratory: Clinical Reasoning for Genetic Test (Attach the clinic note) *** is a *** year old patient with ***. In addition, our patient has a significant family history of ***. See clinic note for additional information. -What laboratory and/or clinical testing have been performed to date (genetic and other testing)? -Why is genetic testing necessary at this time? For the purpose of establishing a diagnosis, we are recommending the aortopathy gene panel. This test includes genes associated with syndromic and non-syndromic causes of aortopathy, which can have different management and treatment recommendations (see Table 1). -How will the results of the genetic test, whether negative or positive, impact the future management of the member being tested? The table below delineates three major aspects of surveillance or management and the differences due to the genetic cause. These three examples illustrate the need for the aortopathy gene panel for our patient. Because we cannot make the diagnosis based on the clinical evaluation alone we need genetic testing to clarify surveillance and contraindications. It is obvious that the specific diagnosis has a significant impact on medical management and surveillance. Stop the need for further diagnostic testing: If a pathogenic variant is found via this panel it will stop the need for additional genetic testing as it relates to the above clinical concerns. Inform on prognosis: Alternative testing methods such as imaging or clinical evaluations alone are not able to provide the same information as the recommended genetic testing and When completed, this form will contain Protected Health Information. Follow your institutional HIPAA guidelines when using this form. therefore cannot be used to make the diagnosis.1,2,3,4,5 The specific diagnosis a genetic test can provide significantly informs on prognosis. Change treatment plan (e.g. medical or surgical decision-making or treatment): There are stark differences in surgical decision-making and treatment depending on which syndrome an individual has. Change surveillance (e.g. annual echocardiograms, either begin or stop): Depending on the result, different surveillance recommendations are made, see Table 1. Without genetic testing, expensive imaging surveillance may be recommended yearly when it is not actually required. Provide information for family members: Identification of a pathogenic variant for our patient will allow at risk family members to get targeted and informative testing. The family members found to not carry the pathogenic variant will avoid unnecessary and costly surveillance.

If this is not known, then please indicate which clinical features increase the probability that this test will provide a diagnosis. The detection rate of the test is variable on clinical phenotype. The clinical features *** has an increased probability the test will provide a diagnosis given @FNAME@ extensive family history of *** -If this is a request is for a gene panel, then please describe why a single gene test is not as useful. A single gene test is not as useful due to the overlap in clinical presentation of the conditions included on this panel. The conditions included in the differential for @FNAME@ present similarly, especially in children, so it would be time-consuming and cost more to sequence genes one by one. -Please list specific guidelines and/or references in support of your request: 1. von Kodolitsch Y, Rybczynski M, Bernhardt A, Mir TS, Treede H, et al.
