Chemically induced Allele Detail
Symbol: Dmdmdx-3Cv
Name: dystrophin, muscular dystrophy; X linked muscular dystrophy 3, Verne Chapman
MGI ID: MGI:1856330
Synonyms: mdx3cv, mdx3cv, mdx3cv, mdxcv3
Gene: Dmd  Location: ChrX:81992476-84249747 bp, + strand  Genetic Position: ChrX, 38.38 cM, cytoband C
Strain of Origin:  C3Ha.Cg-Hprta Pgk1a
Allele Type:    Chemically induced (ENU) (Hypomorph)
Mutation:    Single point mutation
Mutation detailsA T to A transversion creates a novel splice acceptor site 14 bp upstream of the natural site in exon 66. Splicing at this mutant site results in the inclusion of 14 bp of intronic sequence and shifts the reading frame of the encoded mRNA. While a low level of a smaller transcript is expressed from this allele, western blot analysis failed to detect any isoform of protein in various tissues from homozygous mutant mice (J:12150). However, a second report shows that the transcript generated by skipping exons 65 and 66 (D65/66) generates an in-frame transcript that produces low levels of dystrophin (J:250658). (J:12150, J:250658)
Inheritance:    Recessive
