Composition		 Tcrbtm1Slek/Tcrbtm5Slek
Genetic
Background		 Not Specified
Find Mice Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Tcrbtm1Slek mutation (0 available); any Tcrb mutation (99 available)
Tcrbtm5Slek mutation (0 available); any Tcrb mutation (99 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
immune system
abnormal T cell receptor beta chain V(D)J recombination ( J:143738 )
• the Tcrbtm1Slek allele is always rearranged in alphabeta T cells but the Tcrbtm5Slek allele is only rearranged in about half the T cells

hematopoietic system
abnormal T cell receptor beta chain V(D)J recombination ( J:143738 )
• the Tcrbtm1Slek allele is always rearranged in alphabeta T cells but the Tcrbtm5Slek allele is only rearranged in about half the T cells
