Spontaneous Allele Detail
Symbol: Oprm1IAP
Name: opioid receptor, mu 1; intracisternal-A particle insertion
MGI ID: MGI:6388520
Synonyms: Oprm1CXBK
Gene: Oprm1  Location: Chr10:6708593-6988209 bp, + strand  Genetic Position: Chr10, 1.85 cM, cytoband A2
Strain of Origin:  CXB7/ByJ
Allele Type:    Spontaneous (Hypomorph)
Mutation:    Insertion
Mutation detailsSequencing of the gene revealed a 5293 nucleotide insertion in the 3' noncoding region. The inserted sequence is a variant of the intracisternal A-particle elements. Mice carrying this allele express a reduced amount of the major gene transcript. The encoded mRNA contains a normal coding region and an abnormally long untranslated region. (J:283376)
