Mutation origin

• Strain of Origin: C57BL/6J
• Project Collection: B2B/CvDC

Mutation description

• Allele Type: Chemically induced (ENU)
• Mutation: Undefined
• Mutation details: 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 Cfc1^b2b2736.1Clo and b2b2736.2Clo (J:175213)

Notes

Summative Diagnosis:
Mutant Type 1: Cardiovascular Phenotype: Complex congenital heart defects associated with heterotaxy, such as dextroversion with transposition of the great arteries (TGA), unbalanced atrioventricular ventricular septal defect (AVSD), muscular ventricular septal defects (mVSD), hypoplastic right ventricle (RV), common atrium, right aortic arch (RAA), right atrial isomerism, aberrant right subclavian artery, bilateral patent ductus arteriosus (PDA) forming vascular ring, superior-inferior ventricles, and total anomalous pulmonary venous return (TAPVR, intracardiac type)
Noncardiovascular Phenotype: Abnormal thoracic and abdominal organ situs anomalies, such as dextrogastria, right bronchial isomerism, polysplenia, left liver isomerism, inverted liver lobation, malaligned sternal vertebra, and hypoplastic spleen

Mutant Type 2:
Cardiovascular Phenotype: Persistent truncus arteriosus (PTA, Type 1), atrioventricular ventricular septal defect (AVSD), right aortic arch (RAA), and aberrant left subclavian artery forming vascular ring
Noncardiovascular Phenotype: growth retardation, microphthalmia, syndactyly, micrognathia, cleft palate, hypoplastic kidneys, lungs, and thymus

Phenotypic Similarity to Human Syndrome:
Mutant Type 1: Heterotaxy

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/).
