A mentally retarded girl with a sporadically occurring B/F translocation was reexamined with new banding techniques. Chromosome material from the long arm of chromosome 4 was inserted into the long arm of chromosome 20. The segment 4q11 leads to q13 was lost. The formerly reported abnormal segregation of the Gc-system was verified. The localization of the Gc-locus on the lost segment cannot be ruled out.
一名患有偶发性B/F易位的智力发育迟缓女孩采用新的显带技术进行了重新检查。4号染色体长臂的染色体物质插入到了20号染色体长臂中。4q11至q13节段丢失。先前报道的Gc系统异常分离得到了证实。不能排除Gc基因座位于丢失节段上的可能性。
