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. The molecular lesion is an A to C substitution at coding nucleotide 1133 in exon 3 of the cDNA (c.1133A>C, NM_007989). This changes the aspartic acid residue to alanine at position 378 of the encoded protein (p.D378A). (J:175213)

Summative Diagnosis:
Cardiovascular phenotypes: Complex congenital heart disease associated with heterotaxy with right isomerism. Phenotypes observed include dextrocardia/mesocardia, double outlet right ventricle (A,L,L) with anterior placement of the aorta (DORV, Taussig-Bing subtype), right atrial isomerism, unbalanced atrioventricular septal defect (AVSD), double outlet primitive single ventricle, hypoplastic left ventricle (LV).

Noncardiovascular phenotype: Visceral organ situs defects including dextrogastria, right lung isomerism, intestinal malrotation, asplenia. Also observed are hypoplastic thymus, right side diaphragmatic hernia, malaligned sternal vertebra, and craniofacial defects including anencephaly, acrania, agnathia, microstima, microcephaly, low set ears, proboscis, cylcopia, and anophthalmia.

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/).
