Strain of Origin:  C3.SW-H2b/SnJ
Mutation
description
Allele Type:    Spontaneous
Mutation:    Intragenic deletion
 
Mutation detailsThis spontaneous mutation has a deletion of one adenine in exon 1 at position 1559 which results in a frameshift leading to a premature stop codon predicted to yield only a 211 amino acid protein rather than the full-length 1233 amino acids. Western blot analysis using a C-terminus specific antibody failed to detect a protein product in liver extracts of homozygotes. (J:163661)
Inheritance:    Semidominant
