Strain of Origin:  C57BL/6J
Allele Type:    Chemically induced (ENU)
Mutation:    Single point mutation
Mutation detailsENU mutagenesis caused an A to T transversion at the third base position of the 5' splice donor site of intron 19. RT-PCR using primers for exon 15 and exon 21 detected shorter transcripts and no wild-type transcript in hypothalamus of homozygous mutant mice. Sequence analysis revealed that these shorter transcripts are missing exon 19. The authors predict the protein will be missing a 51 amino acid region within the carboxy terminus. (J:40364)
Inheritance:    Semidominant
