摘要
X 四体综合征或 48,XXXX 是一种罕见的性染色体非整倍体。我们对一名发育迟缓的女性患者的 X 四体综合征的父母来源进行了分析;所有四条 X 染色体均来自母亲,没有来自父亲的性染色体。这一发现表明,母系和父系非分离或多体拯救是罕见的偶发并存现象。为了进行比较,我们对与男性发育迟缓有关的 48,XXYY 的机制进行了分析。
Uniparental maternal tetrasomy X co-occurrence with paternal nondisjunction: investigation of the origin of 48,XXXX.
Tetrasomy X or 48,XXXX is a rare sex chromosome aneuploidy. The parental origin of tetrasomy X in a female patient with developmental delay was analyzed; all four X chromosomes were derived from the mother, and there were no paternally derived sex chromosomes. This finding indicates a rare incidental co-occurrence of maternal and paternal nondisjunction or polysomy rescue. The mechanism of 48,XXYY, which is related to developmental delay in males, was analyzed for comparison.
