Strain of Origin:  old mutant of the mouse fancy
Allele Type:    Spontaneous
Mutation:    Single point mutation
Mutation detailsA G-to-A transition point mutation at position 329 was shown by revertant analysis to be responsible for the mutant phenotype seen in the brown mutant. This mutation is predicted to change a cysteine residue to a tyrosine in the encoded protein. Three other point mutations in the brown sequence were identified, but do not contribute to the mutant phenotype. (J:44435)
Inheritance:    Recessive
