Strain of Origin:  C57BL/6J
Project Collection: B2B/CvDC
Allele Type:    Chemically induced (ENU)
Mutation:    Single point mutation
Mutation detailsThis ENU-induced mutation was isolated in a screen at the University of Pittsburgh. It is a subline of b2b2025Clo. The molecular lesion for this subline is attributed to a G-to-T substitution at coding nucleotide position 445 (c.445G>T) in exon 4 of the cDNA (c.445G>T). This changes the glutamic acid residue to a stop at position 149 of the expressed protein (p.E149*). (J:175213) Additional incidental mutations were detected in sequencing for the causative mutation, Ccdc39b2b2025.1Clo, and may be present in stocks carrying this mutation.

Summative Diagnosis:
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

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/).
