There are three potential karyotype scenarios associated with Turner syndrome.

与综合相关的潜在核型有三种。

The least common karyotype in Turner syndrome is where there's only a part of the X chromosome missing.

综合中最不常见的核型X染色体只有部分缺失。

Klinefelter syndrome is diagnosed with a karyotype which visualizes each chromosome including the X, Y, and extra X chromosomes.

核型分析可观察到患者的每条染色体，包括X、Y与额外的X染色体，可用来确诊Klinefelter综合。

A karyotype can be done before birth with an amniocentesis or at any time after birth with the blood test.

核型分析在出生前就可以用羊膜穿刺术取样或在出生后采血取样。

This can also happen at some point during mitosis, and the result is another mosaic karyotype.

这种情况也可能发生在有丝分裂过程中的某个时刻，结成另一个马赛克核型。

Have you had a karyotype test to determine your chromosomes?

你有没有做过染色体核型检测来确定你的染色体类型？

And so this would be a karyotype or a picture of all the chromosomes in an individual.

因此，这一张个体的染色体核型图，展示了所有染色体。

Additionally, a karyotype can be done to look for chromosomal abnormalities and specific genetic tests can be ordered if there's a family history of Fragile-X syndrome.

此外，可进行核型分析以寻找染色体异常，如有脆性X染色体综合家族史，可以进行定的基因检测。

The next most common scenario is mosaicism, meaning the individuals have some cells in their body with the 45, X karyotype and others with a 46, XX karyotype.

另一种最常见的情况嵌合体，这意味着个体体内的一些细胞具有45，X核型，而另一些细胞具有46，XX核型。

Just how many of these abnormalities linked with Turner syndrome are actually present depends on the proportion of cells the person has with the 45, X karyotype.

这些与综合相关的异常会出现多少，取决于一个人拥有45，X染色体核型细胞的比例。

Most commonly, an entire X chromosome is missing, giving a 45, X karyotype - in other words, the person only has 45 chromosomes, missing one of the X chromosomes.

最常见的整条X染色体缺失，成 45，X核型；换句话说，患者的细胞内只有45条染色体，缺失了一条X染色体。
