CHIPS for genetic testing to improve a regional clinical genetic service. (5th September 2014) - Niida, Y.
Abstract In current practice of clinical genetics, molecular diagnosis has become more widely used than ever before. DNA diagnosis is important for appropriate medical care of the patient, and proper genetic counseling to the family. However, genetic testing of orphan disease cannot always be performed easily. In multiple congenital anomalies (MCA) syndromes by monogenic cause, the broad mutational spectrum and large size of responsible genes often make molecular diagnosis expensive and cumbersome. We solve this problem with on‐demand genetic testing by CHIPS (CEL nuclease mediated heteroduplex incision with polyacrylamide gel electrophoresis and silver staining) technology, which is the ultimately conventional and economical mutation screening system. In this article, we show eight patients with MCA syndromes who were recently treated at our hospital, and demonstrate that CHIPS successfully offers efficient and inexpensive genetic testing and facilitates clinical genetic service in our local region.
