This 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 b2b1625.1Clo and b2b1625.2Clo

Summative Diagnosis:
Mutant Type 1:
Cardiac phenotype: Double outlet right ventricle (DORV)/overriding aorta (Ao), atrioventricular septal defect (AVSD)
Noncardiac phenotype: Anopthalmia, duplex kidneys

Mutant Type 2:
Cardiac phenotype: Persistent truncus arteriosus (PTA), aortic arch anomalies, vascular ring
Noncardiac phenotype: Agnathia, microstomia, holoprosencephaly, omphalocele, low set ears

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/).
