A case of trisomy 22 liveborn female baby with multiple congenital anomalies is described.
摘要作者报告一例具有多种先天性异常的三染色体22症的婴。
So this fetus presented seeral signs of trisomy 21, including the hypoplasia of the nasal bone, hypodontia, micrognathia, and hypospadias.

Polysomy, which includes trisomy, is the condition in which one or more chromosomes are represented more than twice in the cell.

Sometimes though, one parent might contribute one chromosome too many, which is called trisomy, or one chromosome less, which is called monosomy.
但是有时候，双亲中可能会贡献多于条染色，这被为三；或者少条染色，为单。
Since trisomy 15 isn't compatible with life, the fetus only survives only if they lose one copy of the chromosome in the early embryo, called trisomy rescue.
15号染色三胎儿不能存活，要想存活就必须在胚胎早期丢失条染色，这过程为三染色自救。
