The murineagoutilocus regulates a switch in pigment synthesis between eumelanin (black/brown pigment) and phaeomelanin (yellow/red pigment) by hair bulb melanocytes. We recently described a spontaneous mutation,hypervariable yellow(Ahvy) and demonstrated thatAhvyis responsible for the largest range of phenotypes yet identified at theagoutilocus, producing mice that are obese with yellow coats to mice that are of normal weight with black coats. Here, we show thatagoutiexpression is altered both temporally and spatially inAhuymutants.Agoutiexpression levels are positively correlated with the degree of yellow pigmentation in individualAhvy, mice, consistent with results from other dominant yellowagoutimutations. Sequencing of 5’ RACE and genomic PCR products revealed thatAhvyresulted from the integration of an intracisternal A particle (IAP) in an antisense orientation within the 5’ untranslatedagoutiexon 1C. This retrovirus-like element is responsible for deregulatingagoutiexpression inAhvymice;agoutiexpression is correlated with the methylation state of CpG residues in the IAP long terminal repeat as well as in host genomic DNA. In addition, the data suggest that the variable phenotype ofAhvyoffspring is influenced in part by the phenotype of theirAhvyfemale parent.
