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 was isolated in a screen at the University of Pittsburgh. The molecular lesion is a T to C substitution at coding nucleotide 197 in exon 3 of the cDNA (c.197T>C, NM_027725). This changes the leucine residue to a proline at position 66 of the encoded protein (p.L66P). Additional incidental mutations were detected in sequencing for the causative mutation, Daw1^b2b1584Clo, and may be present in stocks carrying this mutation.

Notes

Summative Diagnosis:
Laterality defects including situs inversus totalis and heterotaxia with congenital heart disease: dextrocardia, double outlet right ventricle (DORV), possible crisscross heart, and bilateral inferior vena cavae (IVC), and right aortic arch (RAA)
Noncardiac phenotype: Abnormal thoracic and abdominal organ situs anomalies, such as dextrogastria, malaligned sternal vertebra, liver isomerism, left lung isomerism, and hypoplastic spleen/asplenia. Airway cilia were slow and dyskinetic

Phenotypic Similarity to Human Syndrome: Kartagener's Syndrome, Primary Ciliary Dyskinesia, 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/).
