This protocol is specific to genetic testing and explicitly aims to both strengthen clinical care and enhance research. Probands will provide biological specimens for genetic testing and will be required to be enrolled on a primary protocol, which will execute the primary clinical and research evaluations. This protocol serves as a vehicle for a programmatic effort that includes standardized phenotyping, test ordering through the Clinical Research Information System (CRIS), sample collection and isolation, nucleic acid analysis, bioinformatics, clinical interpretation, reporting in CRIS, genetic counseling, and supporting effective use of genomics as a research tool throughout the institute. Overall, increased process standardization will support data integrity and efficiency while still accommodating the need for investigator flexibility.
