摘要:
Dear Editor,
Translocations of the same chromosomal fragments to two or more different chromosomes in different somatic cell lineages are referred to as jumping translocations (JTs).1 JTs have been mainly reported in hematological malignancies but have been observed in rare instances also as constitutional chromosomal aberrations.2 The underlying JT mechanism remains unclear,however.
