Strain of Origin:  C57BL/6J
Project Collection: B2B/CvDC
Allele Type:    Chemically induced (ENU)
Mutation:    Undefined
Mutation detailsThis ENU-induced mutation line was isolated in a screen at the University of Pittsburgh. More than one mutation in this line results in a discernible phenotype in a homozygous recessive screen. At least two segregating phenotype groups are identified. See b2b370.1Clo and Loxb2b370.2Clo

Summative Diagnosis:
Different mutations causing two independently segregating phenotypes:
Mutant 1: Cardiovascular defects: Right aortic arch (RAA), hypoplastic ascending aorta and brachiocephalic arteries. Non-cardiac defects: Noncardiac defects: Craniofacial defects - proboscis, micrognathia, no oral cavity opening (no mouth), holosproencephaly
Mutant 2 (Lox gene mutation): Cardiovascular defects: Supravalvular aortic stenosis (narrowed ascending aorta), Thickened great artery walls, Biventricular hypertrophy, and Pulmonary artery branch stenosis. Non-cardiac defects: diaphragmatic hernia

Fyler Codes
The Fyler code developed by The Boston Children's Heart Foundation in Boston Children's Hospital provides a hierarchical clinical diagnosis of congenital cardiovascular defects and other disorders. These codes are used to delineate pathology in the mutant mouse models that parallel human disease and can be cross referenced to the International Pediatric and Congenital Cardiac Code (IPCCC) (http://www.ipccc.net/).
