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. 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 Cml5b2b1702.1Clo and Megf8b2b1702.2Clo (J:175213)

Summative Diagnosis:
Mutant Type 1:
Cardiovascular phenotypes: Congenital heart disease associated with with heterotaxy, including dextrocardia, double outlet right ventricle (DORV), Taussig-Bing type DORV, muscular VSD (mVSD), atrioventricular septal defects (AVSD), and coronary fistula

Noncardiovascular phenotype: Dextrogastria, right lung isomerism, omphalocele, gastroschisis

Mutant Type 2:
Cardiovascular phenotypes: Heterotaxy with complex congenital heart disease such as transposition of the great arteries (TGA;{SDD}) and dextrocardia with double outlet right ventricle (DORV;{ILL}).

Noncardiovascular phenotype: anophthalmia, short snout, micrognathia, cleft palate

Phenotypic Similarity to Human Syndrome:
Mutant Type 1:

Mutant Type 2:
Carpenter's syndrome

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/).

Fyler Codes Code Description
602 DORV, ventricular defect committed to aorta
110 Dextrocardia
1100 Atrioventricular canal (endocardial cushion defect)
1320 Ventricular septal defect, muscular
190 Heterotaxy Syndrome
2230 Coronary fistula (arterio-venous or arterio-cameral)
3804 Congenital heart disease
4404 Omphalocele
600 Double outlet right ventricle
610 DORV, Taussig bing
