本文报告一例偶发性B/F易位的弱智女孩。将来自4号染色体长臂的染色体材料插入20号染色体长臂。导致q13的4 q11片段丢失。验证了先前报告的GC系统异常分离。不能排除缺失片段上GC基因座的定位。
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.
