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 Ccdc39b2b2025.1Clo and b2b2025.2Clo (J:175213)

Summative Diagnosis:
Mutant Type 1:
Cardiovascular Phenotype: Heterotaxy presenting with dextrocardia/dextroversion and a spectrum of complex congenital heart disease such as superior-inferior ventricles, overriding aorta/double outlet right ventricle (DORV), DORV Taussig Bing subtype, transposition of the great arteries (TGA), atrioventricular septal defect (AVSD), perimembranous and muscular ventricular septal defects (VSD), interrupted aortic arch (IAA), aberrant left subclavian artery forming incomplete vascular ring and dual inferior vena cava (IVC), and right/left atrial isomerism
Noncardiovascular Phenotype: Abnormal thoracic and abdominal organ situs anomalies, such as dextrogastria/midline stomach, hypoplastic spleen/asplenia, left lung isomerism, and midline liver. Airway cilia are immotile

Mutant Type 2:
Cardiovascular phenotype: Double outlet right ventricle (DORV), hypoplastic pulmonary artery, atrioventricular septal defect (AVSD), right aortic arch (RAA), ventricular non-compaction, and aberrant left subclavian artery forming incomplete vascular ring
Noncardiovascular phenotype: Right microphthalmia and syndactyly

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/).
