Abstract

Balanced complex chromosomal rearrangements (BCCR) encompass a heterogeneous group of rare chromosomal aberrations. In this paper, we report three cases of BCCRs. In two the probands were referred for either genetic counseling or prenatal management. One case was ascertained after chromosome analysis performed because of psychiatric manifestations; this was an isolated finding. We also outline the molecular cytogenetic techniques, which were essential in confirming and precisely delineating the BCCRs identified in these patients. In addition the various aspects of genetic counseling for this type of chromosomal rearrangement, highlighting the details particular to each individual case are discussed. We discuss the classification for this type of chromosomal mutation.

至少有三条染色体和三个或更多断点的平衡复杂染色体重排(BCCR):报告三例新病例
平衡复杂染色体重排(BCCR)包含一组罕见的染色体畸变异质。本文报告3例bcrs。在两个先证者被转介进行遗传咨询或产前管理。1例因精神表现经染色体分析确诊;这是一个孤立的发现。我们还概述了分子细胞遗传学技术,这对于确认和精确描述这些患者中发现的bcrs至关重要。此外,遗传咨询的各个方面,为这种类型的染色体重排,突出的细节,具体到每个个案进行了讨论。我们讨论这类染色体突变的分类。
