Spontaneous Allele Detail
Symbol: Map1am1J
Name: microtubule-associated protein 1 A; mutation 1, Jackson
MGI ID: MGI:5774956
Synonyms: nm2719
Gene: Map1a  Location: Chr2:121120081-121141313 bp, + strand  Genetic Position: Chr2, 60.37 cM
Strain of Origin:  C57BLKS/J-Npc1spm/J
Allele Type:    Spontaneous
Mutation:    Intragenic deletion
Mutation detailsA spontaneous mutation results in a 8 bp deletion and 1 bp insertion. This mutation results in a frame shift, deleting 297 amino acids from the C terminus of the heavy chain sand loss of the entire LC2 light chain. Western blot analysis confirmed production of a truncated heavy chain. (J:220153)
Inheritance:    Recessive
