Abstract
Various heteromorphisms of the 9q heterochromatic area have been reported. In most instances, the extra G positive band is accompanied by an extra C band. We describe a family where the extra G band is totally euchromatic and does not include an extra C band. It is not clear whether these two types of variant chromosome 9 arose from a similar mechanism.
摘要
已有关于9号染色体异染色质区域各种异态性的报道。在大多数情况下，额外的G阳性带伴有额外的C带。我们描述了一个家系，其中额外的G带完全是常染色质，且不包括额外的C带。尚不清楚这两种类型的9号变异染色体是否由相似机制产生。
