Mutation
description
Allele Type:    Spontaneous
Mutation:    Transposon insertion
 
Mutation detailsA complex rearrangement involving the deletion of 3 bp of exon C and all of exons D and E (a total of 779 bp) and the in-frame insertion of a 5'-truncated LINE-1 retrotransposon (~2.4 kb). The deletion is predicted to elminate the final 21 residues of the CAPN3 binding site. Low levels of expression of the partial LINE sequence were detected by RT-PCR analysis. (J:74611)
Inheritance:    Recessive
