Abstract
Two unrelated patients are presented. In the first mosaicism with normal cells and cells trisomic for the distal long arm (q2) of chromosome 15 was found. The 15q2 trisomy was due to a chromosome 14, to the long arm of which an extra 15q2 region was attached (14pter----14q32::15q22----15qter). In the second trisomy 15q2 was present as a consequence of a balanced t(7;15)(p22;q15) translocation in the mother.
摘要
现报告两例不相关患者。第一例患者发现存在正常细胞以及15号染色体长臂远端（q2）三体细胞的嵌合体。15q2三体是由于14号染色体，在其长臂上附着了一个额外的15q2区域（14pter----14q32::15q22----15qter）。第二例患者的15q2三体是其母亲平衡易位t(7;15)(p22;q15)的结果。
