Mutation origin

• Strain of Origin: C57BL/6J
• Project Collection: B2B/CvDC

Mutation description

• Allele Type: Chemically induced (ENU)
• Mutation: Single point mutation
• Mutation details: This ENU-induced mutation was isolated in a screen at the University of Pittsburgh. It is a subline of b2b508Clo. The molecular lesion is a C to T substitution at coing nucleotide 2381 in exon 16 of the cDNA (c.2381C>T, NM_011417). This cahnges the threonine residue to isoleucine at position 794 of the encoded protein (p.T794I). (J:175213) Additional incidental mutations were detected in sequencing for the causative mutation, Smarca4^b2b508.1Clo, and may be present in stocks carrying this mutation.

Summative Diagnosis:
Mutant Phenotype I: Cardiac defects: DORV, AVSD, VSD. Noncardiac defects: Microcephaly, micrognathia, anopthalmia.

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 Code ID	Code Description
0600	Double outlet right ventricle
0606	DORV + AVSD (AV canal)
1100	Atrioventricular canal (endocardial cushion defect)
1300	Ventricular septal defect
4163	Micrognathia
4310	Microcephaly
4864	Anophthalmia
