Mutation
description
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 a T to C substitution at coding nucleotide 1565 in exon 16 of the cDNA (c.1565T>C, NM_175138). This changes the isoleucine residue to threonine at position 522 of the encoded protein (p.I522T). (J:175213) Additional incidental mutations were detected in sequencing for the causative mutation, Dnai1b2b1526Clo, and may be present in stocks carrying this mutation.

Notes
Summative Diagnosis:
Cardiovascular phenotype: Situs inversus totalis and heterotaxy with complex congenital heart disease such as dextrocardia, dual inferior vena cava (IVC), aortic arch stenosis, and biventricular hypertrophy
Noncardiovascular phenotype: Abnormal thoracic and abdominal organ situs anomalies, such as dextrogastria, malaligned sternal vertebra, hypoplastic spleen, liver isomerism, and left lung isomerism. Also observed were micrognathia, short snout, and immotile tracheal 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/).
