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 b2b227Clo. The molecular lesion is a T to A substitution at coding nucleotide 2978 in exon 20 of the cDNA (c.2978T>A, NM_001081393). This changes the methionine residue to lysine at position 993 of the encoded protein (p.M993K). (J:175213) Additional incidental mutations were detected in sequencing for the causative mutation, Odad2b2b227.1Clo, and may be present in stocks carrying this mutation.

Summative Diagnosis:
Mutant Type 1:
Cardiovascular phenotype: Dextrocardia/mesocardia and congenital heart disease associated with heterotaxy, such as double outlet right ventricle (DORV), atrioventricular (AVSD) and ventricular septal defects (VSD), right aortic arch (RAA), right atrial isomerism (RAI), and dual inferior vena cava (IVC)
Noncardiovascular phenotype: Abnormal thoracic and abdominal organ situs anomalies, such as dextrogastria, hypoplastic spleen, inverted liver lobation, and malaligned sternal vertebra. Also observed were cystic lungs and immotile/slow/dyskinetic airway cilia

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/).
