We have restudied a fibroblast cell line from a female with marked manifestations of X linked hypohidrotic ectodermal dysplasia (HED) and a balanced X;9 translocation. Chromosome analysis showed a karyotype of 46,X,t(X;9)(q13.1;p24) with an Xq breakpoint distal to the one previously reported. The significance of the cell line, previously unrecognised, for the mapping and eventual cloning of the HED locus is discussed.
我们对一名患有明显X连锁少汗性外胚层发育不良(HED)且有平衡的X;9易位的女性的成纤维细胞系进行了重新研究。染色体分析显示核型为46,X,t(X;9)(q13.1;p24),Xq断点位于先前报道的断点远端。讨论了该先前未被识别的细胞系对于HED基因座定位及最终克隆的意义。
