Variable expressivity and incomplete penetrance are common for numerous mutations. In most cases the reasons behind these phenomena remain obscure. Caused by the insertion of a murine retrotransposon into intron 6 of the Axin locus, the Axin(Fu) mutation induces alternative splicing and ultimately leads to abnormal tail development in mice.

The Axin(Fu) mutation is caused by an IAP insertion. In a small percentage of mice, the Axin(Fu) mutation disappears and is not observed in the next generation. In these mice, [Axin(Fu)]/+, the IAP is absent and Axin(Fu) has reverted to the wild allele. Concomitantly with the loss of IAP, there is widespread reorganisation of numerous microsatellite loci(More)
AxinFu is a mutation in mice that causes fused tails and other developmental abnormalities as a result of insertion of an intracisternal-A particle (IAP), a murine retrotransposon, into intron 6. In a small percentage of offspring we found that the mutant allele reverts to wild-type through loss of the insertion with concomitant disappearance of the mutant(More)
Hybrid sequences have been described previously that consist of a 5' region homologous to ORF2 of LINEs and a 3' end that shares homology with a sequence located in the first intron of Cepsilon immunoglobulin. The present investigation has revealed 14 new sequences from seven murine species, that show high homology to those observed earlier. Database search(More)
