Supplementary Material for: A New Case of an Inherited Reciprocal Translocation in Cattle: rcp(13;26)(q24;q11)

This study reports on a unique balanced reciprocal chromosome
translocation detected in a phenotypically normal cattle dam and her
calf. CBG-, GTG-banding and FISH using bovine whole-chromosome and
telomere probes were applied. The analyses showed that the breakpoints
were located near to the centromere in chromosome 26 (q11) and
exceptionally close to the telomere in chromosome 13 (q24). The whole
euchromatin segment of chromosome 26 was translocated onto chromosome
13. The distal end of chromosome 13 was translocated to the
subcentromeric region of chromosome 26. We describe this aberration as a
balanced reciprocal translocation rcp(13;26)(q24;q11). It appears that
this aberration was maternally derived and may have originated de novo
in the dam.
