Phenotypic Description

Homozygous whitebelly mice exhibit a white spot on the belly. The size of the belly spot in whitebelly mice is smaller than the spot observed in splotch2 animals and never extends to form a belt.

Nature of Mutation
Whitebelly was found to be allelic with splotch2, an ENU induced allele of the Adamts20 gene, in which a mutation responsible for the classical belted phenotype was identified (1).
 
Please see the record for splotch2 for more information about Adamts20.
