Strain of Origin:  C57BL
Allele Type:    Spontaneous
Mutation:    Single point mutation
Mutation detailsAn A to T transversion at the invariant 3' AG splice acceptor of intron 3 was identified in this allele. This mutation abrogates the normal splicing of intron 3, resulting in the generation of four aberrantly spliced mRNA transcripts. Two of these Pax-3 transcripts make use of cryptic 3' splice sites within the downstream exon, generating small deletions which disrupt the reading frame of the transcripts. A third aberrant splicing event results in the deletion of exon 4, while a fourth retains intron 3. These aberrantly spliced mRNA transcripts are not expected to result in functional Pax3 proteins.
