T(1E2.1;8B1.2)2Lub

Position 101,775,857 of chromosome 1 is fused to position 33,249,461 of chromosome 8. One extra base, T, is found in between the fused ends. The breakpoint on chromosome 1 falls in the first intron of Cntnap5b. No known genes are located near the breakpoint in chromosome 8. RT-PCR confirms the absence of Cntnap5b expression in brains from homozygous mice. (J:144618)
