Strain of Origin:  fancier's dancing mouse
Allele Type:    Spontaneous
Mutation:    Intragenic deletion
Mutation detailsA single nucleotide deletion (G) at position 2426 of the Espn gene results in a frameshift mutation and premature stop in the C-terminal actin binding domain. Normal levels of mRNA are observed, but no accumulation of protein is observed in the jerker mouse. (J:53411)
