ReCAP: the Registry of Cytogenetic Abnormalities and Phenylketonuria

The Registry of Cytogenetic Abnormalities and Phenylketonuria (ReCAP) is a multicenter collaborative registry of information on patients with constitutional cytogenetic abnormalities or hyperphenylalaninemia (HPA). Data are entered by microcomputer at four contributing centers. Records are then electronically transmitted to the coordinating center, where the composite cytogenetic and hyperphenylalaninemia databases are maintained on a mainframe computer. A set of programs, known as the ReCAP ISCN Translator, is used to create additional database records describing in detail the chromosome abnormalities present in each patient. The ReCAP computer system permits rapid and flexible retrieval of cases on the basis of any combination of laboratory, clinical, psychometric, or genetic characteristics contained within the databases. Special procedures protect patient confidentiality and assure that ReCAP data are of consistently high quality. Qualified investigators may use ReCAP as a resource for a variety of scientific studies.
