Pericentric inversion of chromosome 4 can give rise to recombinant chromosomes by duplication or deletion of 4p. We report on a familial case of Wolf-Hirschhorn Syndrome characterized by GTG-banding karyotypes, FISH, and array CGH analysis, caused by a recombinant chromosome 4 with terminal 4p16.3 deletion and terminal 4q35.2 duplication. This is an aneusomy due to a recombination which occurred during the meiosis of heterozygote carrier of cryptic pericentric inversion. We also describe the adulthood and prenatal phenotypes associated with the recombinant chromosome 4.
4号染色体的臂间倒位可通过4p的重复或缺失产生重组染色体。我们报告了一例家族性Wolf-Hirschhorn综合征病例,通过GTG带型核型分析、荧光原位杂交(FISH)和阵列比较基因组杂交(array CGH)分析,发现该病例由一条重组4号染色体引起,该染色体末端4p16.3缺失和末端4q35.2重复。这是一种由于隐性臂间倒位杂合子携带者减数分裂期间发生重组导致的非整倍体。我们还描述了与重组4号染色体相关的成人期和产前表型。
