Spontaneous Allele Detail
Symbol: Lamc2jeb
Name: laminin, gamma 2; junctional epidermolysis bullosa
MGI ID: MGI:3609880
Gene: Lamc2  Location: Chr1:153122756-153186447 bp, - strand  Genetic Position: Chr1, 65.26 cM, cytoband H1
Strain of Origin:  129X1/SvJ
Allele Type:    Spontaneous (Hypomorph)
Mutation:    Insertion
Mutation detailsSequencing of mutant genomic DNA revealed the presence of a single murine leukemia virus long terminal repeat (MLV LTR) insertion of 560 bp within the eighteenth intron. Northern blot and RT-PCR analysis detected an aberrant transcript that retains intron 18 and the LTR, and introduces a TAG translational stop codon in intron 18. However, a correctly spliced WT transcript is also produced at low abundance suggesting that this allele acts as a hypomorph. A noncomplementation test with a null allele of this gene further confirmed that the insertion is the cause of the mutant phenotype. (J:158873)
