Partial duplication of 10q is a recognizable clinical entity. In most of the reported cases, the trisomic segment is identified by a balanced translocation state in a parent. Verification remains a problem in de novo cases. However, the recent availability of whole chromosome probes allows for confirmatory diagnosis of suspected cases. We describe a case of de novo duplication (10q) with verification using DNA in situ hybridization.
10号染色体长臂部分重复是一种可识别的临床病症。在大多数已报道的病例中,三体片段是通过父母一方的平衡易位状态确定的。在新发(从头发生)病例中,确诊仍然是个问题。然而,全染色体探针的出现使得疑似病例的确诊成为可能。我们描述了一例通过DNA原位杂交进行确诊的新发(10q)重复病例。
