Strain of Origin:  SB/Le
Allele Type:    Spontaneous
Mutations:    Insertion, Translocation
Mutation detailsAn approximately 4 MB region of the X chromosome that includes at least 13 known genes (spanning from Ofd1 to Mid1) was translocated to the Y chromosome adjacent to the pseudoautosomal region. Increased RNA expression of Msl3, Tlr7, Tmsb4x and Rab9 was detected in follicular B cells. (J:109758, J:111064, J:140028)
