Mouse Strain information
Added 06/02/2006
Last Edited 10/05/2014
Strain name: C57BL/6JSfdAnu-Lcp2twm/AnuApb
Nickname: T-wimp
Strain designation name: C57BL/6JSfdAnu-Lcp2twm/AnuApb
Strain Types Mutant strain
Genetic Details Chemically induced : ENU
Mode of Inheritance Recessive
1.  Affected Gene Name: lymphocyte cytosolic protein 2  
Chromosome 11
Affected Gene Symbol Lcp2
Protein expression of altered gene: Reduced
Genetic alteration of gene: ENU induced mutation. A T-to-G transversion in intron 12 that results in altered mRNA splicing. Homozygous mutant mice express two processed transcripts, the normal, wild type mRNA and a second lacking exon 12 and having a premature stop codon in exon 13. T cells of mutant mice express reduced levels of SLP76/LCP2.
Location on chromosome (bp): 33946920-33992295 bp, + strand (From VEGA annotation of NCBI Build 37)
