Radiation induced Allele Detail
Symbol: ax
Name: nonagouti; lethal nonagouti
MGI ID: MGI:1855944
Synonyms: a(x)
Gene: a  Location: Chr2:154950204-155051012 bp, + strand  Genetic Position: Chr2, 76.83 cM
Strain of Origin:  (C3H/Rl x 101/Rl)F1
Allele Type:    Radiation induced
Mutation:    Intergenic deletion
Mutation detailsThis allele comprises a deletion of approximately 100 kb, which does not affect agouti coding sequences, but begins 4 kb 3' of the last exon, and thus may affect coat color by removing an agouti 3' enhancer. The Ahcy gene, which codes for the enzyme S-adenosylhomocysteine hydrolase (SAHase), is contained within a 20 kb region within the a(x) deletion. (J:17867)
Inheritance:    Other (see notes)
