Partial monosomy or trisomy resulting from crossing over within a rearranged chromosome 1 总被引:2,自引:0,他引:2
Two sibs, both monosomic for the same portion of lq (q25q32), had similar severe mental and physical retardation. An older sib was found to be trisomic for the same portion of 1q and less severely affected. These partially monosomic and partially trisomic No. 1 chromosomes resulted from meiotic crossover in the mother, who is a balanced hetero-zygote of the type 46.XX, ins (1) (p32q25q32). 相似文献
