46,XY,FraXq27:2%.，流产过两次是染色体导致的吗?46, XY, FraXq 27:2 %. Did you have two miscarriages caused by chromosomes?

陈凤林教授指出染色体46,XY,FraXq27:2%.只是表现出它的多汰性而已并不致病，流产一定有其他原因，比如免疫因素，宫腔形态因素，内分泌因素，百分之九十的流产可以孕前干预治疗。

Professor Chenfenglin pointed out chromosomes 46, XY, FraXq 27:2 %. It is only that it shows that its versatility is not pathogenic. There must be other reasons for miscarriage, such as immune factors, uterine morphological factors, endocrine factors, and 90 % of miscarriages can be treated before pregnancy.

其实夫妇染色体异常不会导致习惯性流产。原因是，染色体异常形成于精卵结合之初，染色体异常有三种情况：

In fact, couples with chromosomal abnormalities do not lead to habitual miscarriage. The reason is that chromosomal abnormalities are formed at the beginning of sperm egg binding. There are three types of chromosomal abnormalities:

致死型异常;致残型异常;携带型异常。致死型，是染色体严重变异，结局是胚胎枯萎而自然流产，不会有出生婴儿。

Lethal abnormalities; Disabling abnormalities; Portable anomaly. The lethal type is a serious chromosome variation. The outcome is that the embryo withers and naturally miscarries, and there will be no baby born.

The disability type is a moderately abnormal chromosome, and it is mostly a change in the number of chromosomes.

致残型,是染色体中度异常，多是染色体数量变化，如21三体，22三体，特纳综合征(多一条Y染色体)等出生的都是残疾人，基本都无生育能力。

For example, 21 trisomes, 22 trisomes, Turner syndrome(more than one Y chromosome), etc., are all born with disabilities and are basically infertile.

携带型，是轻度染色体异常，如平衡易位、倒位[46，XY，t(5，12)]等，遗传信息并不少，只是染色体片段发生位移，这样的人外表和生殖腺正常，也不会导致流产，充其量出生的后代染色体与上代一样而已。正所谓龙生龙，凤生凤，老鼠生来会打洞。

Portable type, is a mild chromosomal anomaly, such as equilibrium transposition, inversion[ 46, XY, T(5, 12)] And so on, there is a lot of genetic information, but the chromosomal fragments are displaced. Such a person's appearance and gonad are normal, and it will not lead to miscarriage. At best, the offspring born have the same chromosomes as the previous generation. The so-called dragon born Dragon, Phoenix born Phoenix, mice born to make holes.
